Rule 2 DEFINITION OF TERMS AND CONSTRUCTION

Section 1. Definition of terms. – For purposes of these Rules, the following terms are defined, as follows:

(a) "Asymmetric or public cryptosystem" means a system capable of generating a secure key pair, consisting of a private key for creating a digital signature, and a public key for verifying the digital signature.

(b) "Business records" include records of any business, institution, association, profession, occupation, and calling of every kind, whether or not conducted for profit, or for legitimate or illegitimate purposes.

(c) "Certificate" means an electronic document issued to support a digital signature which purports to confirm the identity or other significant characteristics of the person who holds a particular key pair.

(d) "Computer" refers to any single or interconnected device or apparatus, which, by electronic, electro-mechanical or magnetic impulse, or by other means with the same function, can receive, record, transmit, store, process, correlate, analyze, project, retrieve and/or produce information, data, text, graphics, figures, voice, video, symbols or other modes of expression or perform any one or more of these functions.

(e) "Digital signature" refers to an electronic signature consisting of a transformation of an electronic document or an electronic data message using an asymmetric or public cryptosystem such that a person having the initial untransformed electronic document and the signer's public key can accurately determine:

i. whether the transformation was created using the private key that corresponds to the signer's public key; and

ii. whether the initial electronic document had been altered after the transformation was made.

(f) "Digitally signed" refers to an electronic document or electronic data message bearing a digital signature verified by the public key listed in a certificate.

(g) "Electronic data message" refers to information generated, sent, received or stored by electronic, optical or similar means.

(h) "Electronic document" refers to information or the representation of information, data, figures, symbols or other modes of written expression, described or however represented, by which a right is established or an obligation extinguished, or by which a fact may be proved and affirmed, which is received, recorded, transmitted, stored, processed, retrieved or produced electronically. It includes digitally signed documents and any print-out or output, readable by sight or other means, which accurately reflects the electronic data message or electronic document. For purposes of these Rules, the term "electronic document" may be used interchangeably with "electronic data message".

(i) "Electronic key" refers to a secret code which secures and defends sensitive information that crosses over public channels into a form decipherable only with a matching electronic key.

(j) "Electronic signature" refers to any distinctive mark, characteristic and/or sound in electronic form, representing the identity of a person and attached to or logically associated with the electronic data message or electronic document or any methodology or procedure employed or adopted by a person and executed or adopted by such person with the intention of authenticating, signing or approving an electronic data message or electronic document. For purposes of these Rules, an electronic signature includes digital signatures.

(k) "Ephemeral electronic communication" refers to telephone conversations, text messages, chatroom sessions, streaming audio, streaming video, and other electronic forms of communication the evidence of which is not recorded or retained.

(l) "Information and communication system" refers to a system for generating, sending, receiving, storing or otherwise processing electronic data messages or electronic documents and includes the computer system or other similar devices by or in which data are recorded or stored and any procedure related to the recording or storage of electronic data messages or electronic documents.

(m) "Key pair" in an asymmetric cryptosystem refers to the private key and its mathematically related public key such that the latter can verify the digital signature that the former creates.

(n) "Private key" refers to the key of a key pair used to create a digital signature.

(o) "Public key" refers to the key of a key pair used to verify a digital signature.

Section 2. Construction. – These Rules shall be liberally construed to assist the parties in obtaining a just, expeditious, and inexpensive determination of cases.
