  • Patent number: 11539516
    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.

  • Patent number: 10655274
    Abstract: A threadlike metallic or metallized reinforcer, for example a thread, film, tape or cord made of carbon steel, at the periphery of which is positioned a layer of metal referred to as “surface metal” chosen from copper, nickel and copper/nickel alloys, is characterized in that this surface metal layer is itself coated, at least in part, with at least one layer of graphene; preferably, there is grafted, to this graphene, at least one functional group which can crosslink to a polymer matrix. This reinforcer of the invention is effectively protected from corrosion by virtue of the graphene present at the surface; advantageously, it can be adhesively bonded directly, without adhesion primer or addition of metal salt, to an unsaturated rubber matrix, such as natural rubber, by virtue of the possible functionalization of this graphene.
