Digitally signed document..

Today for the first time, I digitally signed on the attendance lists given to me by the Computer science dept. The format is in open document spreadsheet (ods) format.

The problem with physical documents is that anybody can tamper with it, take photostat copies and overwrite something etc. But in a digitally signed document, the reader can only view it and if anyone tampers with the document, the signature is invalid.

The tender document for the 2G tendering by the Central govt if it had been signed digitally by the Minister or the bureaucrats, it would not have been possible to tamper with it as done by the minister to favour his people.

Hopefully the popularity of digital signatures will increase.
