Illinois Compiled Statutes

Information maintained by the Legislative Reference Bureau
Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process. Recent laws may not yet be included in the ILCS database, but they are found on this site as Public Acts soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the Guide.

Because the statute database is maintained primarily for legislative drafting purposes, statutory changes are sometimes included in the statute database before they take effect. If the source note at the end of a Section of the statutes includes a Public Act that has not yet taken effect, the version of the law that is currently in effect may have already been removed from the database and you should refer to that Public Act to see the changes made to the current law.

GENERAL PROVISIONS
(5 ILCS 175/) Electronic Commerce Security Act.

5 ILCS 175/Art. 5

 
    (5 ILCS 175/Art. 5 heading)
ARTICLE 5. ELECTRONIC RECORDS AND SIGNATURES GENERALLY

5 ILCS 175/5-105

    (5 ILCS 175/5-105)
    Sec. 5-105. Definitions.
    "Asymmetric cryptosystem" means a computer-based system capable of generating and using a key pair consisting of a private key for creating a digital signature and a public key to verify the digital signature.
    "Certificate" means a record that at a minimum: (a) identifies the certification authority issuing it; (b) names or otherwise identifies its subscriber or a device or electronic agent under the control of the subscriber; (c) contains a public key that corresponds to a private key under the control of the subscriber; (d) specifies its operational period; and (e) is digitally signed by the certification authority issuing it.
    "Certification authority" means a person who authorizes and causes the issuance of a certificate.
    "Certification practice statement" is a statement published by a certification authority that specifies the policies or practices that the certification authority employs in issuing, managing, suspending, and revoking certificates and providing access to them.
    "Correspond", with reference to keys, means to belong to the same key pair.
    "Digital signature" means a type of electronic signature created by transforming an electronic record using a message digest function and encrypting the resulting transformation with an asymmetric cryptosystem using the signer's private key such that any person having the initial untransformed electronic record, the encrypted transformation, and the signer's corresponding public key can accurately determine whether the transformation was created using the private key that corresponds to the signer's public key and whether the initial electronic record has been altered since the transformation was made. A digital signature is a security procedure.
    "Electronic" includes electrical, digital, magnetic, optical, electromagnetic, or any other form of technology that entails capabilities similar to these technologies.
    "Electronic record" means a record generated, communicated, received, or stored by electronic means for use in an information system or for transmission from one information system to another.
    "Electronic signature" means a signature in electronic form attached to or logically associated with an electronic record.
    "Information" includes data, text, images, sound, codes, computer programs, software, databases, and the like.
    "Key pair" means, in an asymmetric cryptosystem, 2 mathematically related keys, referred to as a private key and a public key, having the properties that (i) one key (the private key) can encrypt a message that only the other key (the public key) can decrypt, and (ii) even knowing one key (the public key), it is computationally unfeasible to discover the other key (the private key).
    "Message digest function" means an algorithm that maps or translates the sequence of bits comprising an electronic record into another, generally smaller, set of bits (the message digest) without requiring the use of any secret information such as a key, such that an electronic record yields the same message digest every time the algorithm is executed using such record as input and it is computationally unfeasible that any 2 electronic records can be found or deliberately generated that would produce the same message digest using the algorithm unless the 2 records are precisely identical.
    "Operational period of a certificate" begins on the date and time the certificate is issued by a certification authority (or on a later date and time certain if stated in the certificate) and ends on the date and time it expires as noted in the certificate or is earlier revoked, but does not include any period during which a certificate is suspended.
    "Person" means an individual, corporation, business trust, estate, trust, partnership, limited partnership, limited liability partnership, limited liability company, association, joint venture, government, governmental subdivision, agency, or instrumentality, or any other legal or commercial entity.
    "Private key" means the key of a key pair used to create a digital signature.
    "Public key" means the key of a key pair used to verify a digital signature.
    "Record" means information that is inscribed, stored, or otherwise fixed on a tangible medium or that is stored in an electronic or other medium and is retrievable in perceivable form.
    "Repository" means a system for storing and retrieving certificates or other information relevant to certificates, including information relating to the status of a certificate.
    "Revoke a certificate" means to permanently end the operational period of a certificate from a specified time forward.
    "Rule of law" means any statute, ordinance, common law rule, court decision, or other rule of law enacted, established or promulgated by the State of Illinois, or any agency, commission, department, court, other authority or political subdivision of the State of Illinois.
    "Security procedure" means a methodology or procedure used for the purpose of (1) verifying that an electronic record is that of a specific person or (2) detecting error or alteration in the communication, content, or storage of an electronic record since a specific point in time. A security procedure may require the use of algorithms or codes, identifying words or numbers, encryption, answer back or acknowledgment procedures, or similar security devices.
    "Signature device" means unique information, such as codes, algorithms, letters, numbers, private keys, or personal identification numbers (PINs), or a uniquely configured physical device, that is required, alone or in conjunction with other information or devices, in order to create an electronic signature attributable to a specific person.
    "Signed" or "signature" includes any symbol executed or adopted, or any security procedure employed or adopted, using electronic means or otherwise, by or on behalf of a person with intent to authenticate a record.
    "State agency" means and includes all officers, boards, commissions, courts, and agencies created by the Illinois Constitution, whether in the executive, legislative or judicial branch, all officers, departments, boards, commissions, agencies, institutions, authorities, universities, bodies politic and corporate of the State; and administrative units or corporate outgrowths of the State government which are created by or pursuant to statute, other than units of local government and their officers, school districts and boards of election commissioners; all administrative units and corporate outgrowths of the above and as may be created by executive order of the Governor.
    "Subscriber" means a person who is the subject named or otherwise identified in a certificate, who controls a private key that corresponds to the public key listed in that certificate, and who is the person to whom digitally signed messages verified by reference to such certificate are to be attributed.
    "Suspend a certificate" means to temporarily suspend the operational period of a certificate for a specified time period or from a specified time forward.
    "Trustworthy manner" means through the use of computer hardware, software, and procedures that, in the context in which they are used: (a) can be shown to be reasonably resistant to penetration, compromise, and misuse; (b) provide a reasonable level of reliability and correct operation; (c) are reasonably suited to performing their intended functions or serving their intended purposes; (d) comply with applicable agreements between the parties, if any; and (e) adhere to generally accepted security procedures.
    "Valid certificate" means a certificate that a certification authority has issued and that the subscriber listed in the certificate has accepted.
    "Verify a digital signature" means to use the public key listed in a valid certificate, along with the appropriate message digest function and asymmetric cryptosystem, to evaluate a digitally signed electronic record, such that the result of the process concludes that the digital signature was created using the private key corresponding to the public key listed in the certificate and the electronic record has not been altered since its digital signature was created.

5 ILCS 175/5-115

    (5 ILCS 175/5-115)
    Sec. 5-115. Electronic records.
    (a) Where a rule of law requires information to be "written" or "in writing", or provides for certain consequences if it is not, an electronic record satisfies that rule of law.
    (b) The provisions of this Section shall not apply:
        (1) when its application would involve a construction
    
of a rule of law that is clearly inconsistent with the manifest intent of the lawmaking body or repugnant to the context of the same rule of law, provided that the mere requirement that information be "in writing", "written", or "printed" shall not by itself be sufficient to establish such intent;
        (2) to any rule of law governing the creation or
    
execution of a will or trust, living will, or healthcare power of attorney; and
        (3) to any record that serves as a unique and
    
transferable instrument of rights and obligations including, without limitation, negotiable instruments and other instruments of title wherein possession of the instrument is deemed to confer title, unless an electronic version of such record is created, stored, and transferred in a manner that allows for the existence of only one unique, identifiable, and unalterable original with the functional attributes of an equivalent physical instrument, that can be possessed by only one person, and which cannot be copied except in a form that is readily identifiable as a copy.
(Source: P.A. 90-759, eff. 7-1-99.)

5 ILCS 175/5-120

    (5 ILCS 175/5-120)
    Sec. 5-120. Electronic signatures.
    (a) Where a rule of law requires a signature, or provides for certain consequences if a document is not signed, an electronic signature satisfies that rule of law.
    (a-5) In the course of exercising any permitting, licensing, or other regulatory function, a municipality may accept, but shall not require, documents with an electronic signature, including, but not limited to, the technical submissions of a design professional with an electronic signature.
    (b) An electronic signature may be proved in any manner, including by showing that a procedure existed by which a party must of necessity have executed a symbol or security procedure for the purpose of verifying that an electronic record is that of such party in order to proceed further with a transaction.
    (c) The provisions of this Section shall not apply:
        (1) when its application would involve a construction
    
of a rule of law that is clearly inconsistent with the manifest intent of the lawmaking body or repugnant to the context of the same rule of law, provided that the mere requirement of a "signature" or that a record be "signed" shall not by itself be sufficient to establish such intent;
        (2) to any rule of law governing the creation or
    
execution of a will or trust, living will, or healthcare power of attorney; and
        (3) to any record that serves as a unique and
    
transferable instrument of rights and obligations including, without limitation, negotiable instruments and other instruments of title wherein possession of the instrument is deemed to confer title, unless an electronic version of such record is created, stored, and transferred in a manner that allows for the existence of only one unique, identifiable, and unalterable original with the functional attributes of an equivalent physical instrument, that can be possessed by only one person, and which cannot be copied except in a form that is readily identifiable as a copy.
(Source: P.A. 98-289, eff. 1-1-14.)

5 ILCS 175/5-125

    (5 ILCS 175/5-125)
    Sec. 5-125. Original.
    (a) Where a rule of law requires information to be presented or retained in its original form, or provides consequences for the information not being presented or retained in its original form, that rule of law is satisfied by an electronic record if there exists reliable assurance as to the integrity of the information from the time when it was first generated in its final form, as an electronic record or otherwise.
    (b) The criteria for assessing integrity shall be whether the information has remained complete and unaltered, apart from the addition of any endorsement or other information that arises in the normal course of communication, storage and display. The standard of reliability required to ensure that information has remained complete and unaltered shall be assessed in the light of the purpose for which the information was generated and in the light of all the relevant circumstances.
    (c) The provisions of this Section do not apply to any record that serves as a unique and transferable instrument of rights and obligations including, without limitation, negotiable instruments and other instruments of title wherein possession of the instrument is deemed to confer title, unless an electronic version of such record is created, stored, and transferred in a manner that allows for the existence of only one unique, identifiable, and unalterable original with the functional attributes of an equivalent physical instrument, that can be possessed by only one person, and which cannot be copied except in a form that is readily identifiable as a copy.

5 ILCS 175/5-130

    (5 ILCS 175/5-130)
    Sec. 5-130. Admissibility into evidence.
    (a) In any legal proceeding, nothing in the application of the rules of evidence shall apply so as to deny the admissibility of an electronic record or electronic signature into evidence:
        (1) on the sole ground that it is an electronic
    
record or electronic signature; or
        (2) on the grounds that it is not in its original
    
form or is not an original.
    (b) Information in the form of an electronic record shall be given due evidentiary weight by the trier of fact. In assessing the evidential weight of an electronic record or electronic signature where its authenticity is in issue, the trier of fact may consider the manner in which it was generated, stored or communicated, the reliability of the manner in which its integrity was maintained, the manner in which its originator was identified or the electronic record was signed, and any other relevant information or circumstances.
(Source: P.A. 90-759, eff. 7-1-99.)

5 ILCS 175/5-135

    (5 ILCS 175/5-135)
    Sec. 5-135. Retention of electronic records.
    (a) Where a rule of law requires that certain documents, records or information be retained, that requirement is met by retaining electronic records of such information in a trustworthy manner, provided that the following conditions are satisfied:
        (1) the electronic record and the information
    
contained therein are accessible so as to be usable for subsequent reference at all times when such information must be retained;
        (2) the information is retained in the format in
    
which it was originally generated, sent, or received or in a format that can be demonstrated to represent accurately the information originally generated, sent or received; and
        (3) such data as enables the identification of the
    
origin and destination of the information, the authenticity and integrity of the information, and the date and time when it was sent or received, if any, is retained.
    (b) An obligation to retain documents, records or information in accordance with subsection (a) does not extend to any data the sole purpose of which is to enable the record to be sent or received.
    (c) Nothing in this Section shall preclude any State agency from specifying additional requirements for the retention of records that are subject to the jurisdiction of such agency.

5 ILCS 175/5-140

    (5 ILCS 175/5-140)
    Sec. 5-140. Electronic use not required. Nothing in this Act shall be construed to:
        (1) require any person to create, store, transmit,
    
accept, or otherwise use or communicate information, records, or signatures by electronic means or in electronic form; or
        (2) prohibit any person engaging in an electronic
    
transaction from establishing reasonable requirements regarding the medium on which it will accept records or the method and type of symbol or security procedure it will accept as a signature.
(Source: P.A. 90-759, eff. 7-1-99.)

5 ILCS 175/5-145
