Sony Pictures Digital Signature Digital Signature is the digital signature system for the Sony Pictures digital signature process.

The process involves creating digital signatures that prove the authenticity of the digital file by capturing a signature from a person’s fingerprint.

In the case of Son of Sam, Sony digitally signed the movie digitally using the Sony Digital Signature Service.

The Sony Digital Signatures program has been available to movie studios for years, but Sony introduced it in the digital signing service to provide the process for movie studios to verify a digital file.

It also allows movie studios and their production companies to track and manage the digital files in a way that is faster and more efficient.
