Phone number hashing
Make phone number unrecognizable 'Deed of Signature'
Zynyo has developed a solution to make a phone number unrecognisable in the 'Deed of signing'. The phone number is hashed (one way hash pseudonymisation) using the SHA-256 hashing algorithm.
The purpose of the hash is to reproduce the same code based on an existing piece of data (the 06 number). Each different 06 number produces a unique hash code. By placing this hash code on the document, it can be subsequently determined whether a known 06 number was signed with.
For example, the 06-number used by us as an example provides the following hash code (sha-256): 49c7b1f6d24121078d8f37997b433586fe9a28e2dc4fbd0803eac237ac82255e
This code will appear, together with the protocol used, in the 'Deed of signing' (see image).
