The concept of hash-value plays vital role during investigation of cyber crime. This means recovery of evidence from the scene of crime, mainly hard disc of the computer, so that the integrity of data is not  contaminated or tempered with. Any tempering may give benefit of doubt to the suspect or accused in the court, Kapoor averred.
Hash-value of any computer may be tracked per second by the investigator through a software. It can  be immediately known whether the content found in the hard disc was changed or tempered with after the cyber crime was reported, he claimed.
Concept of maintaining hash value is helpful for investigator as counsel for accused in cyber crime may not challenge it in the court, especially in planned crimes like terrorism, financial fraud, cold blooded murders, robberies and economic offences.
