When we use digital signatures, we try to keep three essential points of data safely:

• Authentication of the document: Inspakt provides knowledge-based authentication such as email verification or text message so those persons can't later say they didn't sign the document.
• Non-repudiation: Signers need to be identified, and the possibility of a signer suggesting they made a mistake in signing or never 'clicked' a button is eliminated.
• Integrity: Documents have not been changed after all parties reached out a consensus on the terms.

For reaching out to these goals, digital signatures use hash functions and Public Key Cryptography (PKC) to provide data integrity, authenticity, and proof of the agreement. Trying to explain the technology of digital signatures can be much more challenging. They are based on mathematical algorithms and advanced cryptographic concepts, a bit more complicated to explain than a pen and ink signature.

A digital signature primarily is a method of verifying an electronic record's authenticity (email, spreadsheet, text file). Authentic means that you know who generated the document and that it hasn't been tampered with in any way since that time.

To ensure authentication, digital signatures use different forms of encryption. Encryption is the act of converting all of the data that one computer sends to another into a format that only the other computer can understand. Authentication is the method of ensuring the data comes from a reliable source. For digital signatures, these two procedures go hand in hand.

Generally, three algorithms are used by a digital signature system. A key generation algorithm is used to generate a public and private key pair. Another signing algorithm is used to create a signature used to give out the private key and a message. Lastly, the signature verifying algorithm is used to verify the message, a signature & the public key.

Besides the use of keys, there is one more possibility to verify the identity of signers and the originality of the document. This option is to use the biometric data of the signers. In order to meet the biometric signature standards, geo-location data, acceleration, pressure, speed, and delta pressure are recorded and sealed in the document in a case. When it is needed by the legal authorities, this data can work as a wet signature and can identify the signers.
