A major health care provider needed a solution for a consistent and secret but personal and readable voter number for one of its clients. On the basis of the existing product requirements document, SHC created the functional specifications document, which was then implemented together with a SHC partner company.
According to this, the voter number is cryptographically deduced from the numbers of approximately 6 million insured persons. After this, it was checked for uniqueness and finally prepared for postal voting.
