Transaction security

Securing transactions: Digital signatures and proof

When completing electronic transactions, all parties need to be sure of the reliability of their mutual commitment. The participants need to be certain that the terms of the agreement (the amount, the date, etc.) have not been, nor will be, modified for the duration of the agreement.
In addition, contracting parties also need to access to an accurate transaction description, in the event of a dispute.

The digital signature: signal commitment

Digital signatures allow participants to formally mark their commitment to information, a wire order, a contract, etc. This signature prevents any one-sided changes to the signed data (protecting its integrity), and also serves to authenticate the signer. Digital signatures replace traditional pen-and-ink signatures, and offer the same legal value.

Signature validation and constitution of proof

Organizations or individuals that receive signed documents need to be able to verify the authenticity of the information. This involves checking that the terms of the agreement have not changed, and that they were approved by the correct person (digital signature validation).
The organization or individual must then create proof of the transaction. This proof contains all of the agreement terms, such as the amounts, dates, parties involved… In the event of litigation between the parties, the organization or individual will be able to rely on this proof.
