WinSesame Certification :
Signature and certification of a file:
The certification of a file consists in saving on a secure server
a digital signature of this file but not the file itself. Any file
of any type has a unique digital signature but from this signature
it is impossible to reconstruct the file. This digital signature
is then associated with a readable signature created by the
signatory of the file. This signature is time stamped by the
server and not by the signatory. It has a unique and
non-modifiable identifier of the signer on the server. In order to
be able to provide proof of the ownership of the file, the
signatory may include in his signature the digital signature of a
private and unique signature file that he is the only one to
possess (private key). The signature is then saved on the server.
The same file can not be signed twice by the same person or not.
The verification procedure will be used as appropriate to:
To ensure that the file conforms to the least byte to the
original which is important in the case of a file offered for
download, transmitted as an attachment, available on a network,
hosted in a cloud etc ... for protect yourself from simple
problems of incomplete download, transmission error etc. or
intentional corruption of a file for the purpose of installing a
malware, spyware, ransomware, virus or takeover of a computer.
To certify the ownership of the file thanks to the unique
identifier contained in the signature plus the private signature
file that the signatory has included in his signature and of which
he is the only one able to provide the original and his digital
signature. Intellectual protection of all types of data: music,
photos, videos, patents. Proof of date of deposit. Legal documents
etc ...
