Showing contexts for: hash value in Ram Kishan Fauji vs State Of Haryana & Ors on 27 February, 2015Matching Fragments
10. In the manner of analysis undertaken by the CFSL, Hyderabad, the CD has been examined and the forensic image was seen to have been authenticated by MD5 Hash (#) value. Hash value is stated to be a result of a calculation (hash algorithm) that could be performed on a string of text, electronic file or entire hard drive's contents. Each hashing algorithm uses a specific number of bytes to store a thumbprint of the contents. The most common hash value, it would appear to be MD5. # MD5 has a particular value which if picked up from a CD, its authenticity is best illustrated by the fact that the memory chip also contains the thumbprint, namely, the hash value MD5. The report from the CFSL, Hyderabad reveals that there were two reports of Read Errors at Sector 7 at Start Sector 320 and Start Sector 30,649. Another important aspect, which it has noted, is that there was no link possible between the digital evidence storage media, namely, the CD and the memory chip that was said to have been the source for the replication of data in the CD. In the manner of explaining the Read Errors, although the report does not say what the Read Errors were, the report from the Truth Labs indicates what exactly they were that there had been a discontinuity in the Pitch contour at 53 seconds and 56 seconds of the recordings. 1st conclusion: CFSL report nails down any prospect of attaching value to authenticity of CD
11. After securing the report from the CFSL, Hyderabad, there is hardly anything left to assess the authenticity of the CD. If the CD cannot stand the test of authenticity by its comparison with its hash value with the source, then the transcript of what has been obtained through its audio footage or what it purports to capture cannot be taken as of any value.
