The evidence to prove facts in a litigation owing to any dispute in the cyber space are computer generated. By virtue of the Information Technology Act, 2000, now the computer generated documents are admitted as evidence under the provisions of the Indian Evidence Act, 1872. There are three types of computer generated documentary evidence. The first type is computer generated calculations and analyses obtained through software operations and information received. The second type is computer generated documents and records that are copies of information obtained from human beings. The third type is the combination of both computer generated calculations and analyses and computer generated documents based on information from human beings. The UNCITRAL Model Law on electronic commerce (1996) deals with the admissibility and evidentiary value of data message. The Model Law is intended to facilitate the use of modern means of communications and storage of information and establishment of a functional equivalent in electronic media for paper-based concepts such as "writing", "signature" and "original". The Model Law also contains rules for electronic commerce in specific areas, such as carriage of goods.
