DNA encryption

Innovation

The General Personal Data Protection Law (LGPD) protects everyone's privacy. It strictly regulates any collection, storage or disclosure activity involving personal data. Personal data such as names, date of birth, address or CPF cannot be used to link databases without prior approval and/or consent.

Strategy

Generally, to allow the use of personal information they use anonymity. In this way, Personnel Records are encoded into a string. In this case, only the manager who encoded the data is able to decode it. However, if there is a small typing error, the coding transforms data from the same person into completely different sequences (figure below). This makes it impossible to match such records across different databases.

Solution

D2DNA offers a solution to this problem: anonymizing personal data by transforming it into DNA sequences. In this way, the similarity between the records is maintained. This encryption technique protects the individual's identity but allows for later connection of databases. Thus, even if the records are slightly different, computational bioinformatics algorithms find the same individual present in several databases.
