Abstract
The invention is notably directed to a method for encoding information. This method first comprises generating an encryption key according to polymorphic features of nucleic acids from one or more entities. Next, information is encrypted based on the generated key. Finally, the encrypted information is encoded into synthetic DNA. Another aspect concerns a method for retrieving information. Consistently with the above encoding scheme, synthetic DNA in provided, which encodes encrypted information. Such information is read by sequencing the synthetic DNA and by decrypting the information read using a decryption key. The latter is generated according to polymorphic features of nucleic acids from one or more entities (e.g., from the legitimate individual(s) requesting access to information). Thus, the encoded information cannot be interpreted unless a suitable decryption key is available. The invention is further directed to related DNA samples and systems, including DNA vaults.
