Join Jungwoo Ryoo for an in-depth discussion in this video Understanding hashing and its role in ensuring data integrity, part of Learning Computer Forensics.
…Hashing plays an important role in computer forensics.…It ensures that a copy of data you're making is remaining identical to…its source.…Hashing refers to the process of transforming an input usually a file…into an output which is a unique string associated with the file.…There are some important characteristics about hashing.…Any slight changes you're making in a file will get amplified in huge…changes in its hash value.…
This makes it very easy to detect changes made to a file either by accident or…on purpose.…Hashing ensures data integrity and…data integrity means no unintended changes are made in the data.…In the context of computer forensics this means evidence drive…remains the same during your investigation.…That is a forensic image or…copy of the evidence drive remains the same throughout your investigation.…Therefore hashing is an essential part of your compter forensics investigation.…
Any non-trivial computer forensics tools should come equipped with an ability to…produce hash values.…Now we'll do a quick demo of hashing on a Linux operating system.…
