Abstract: In a system and methods to verify data integrity and origin authenticity of signed elements in an arbitrary blockchain, a block is signed using a first digital signature algorithm. A hash on the signed first block value is computed. A parallel assurance of blockchain signatures (“PABS”) record includes a cryptographic message, comprising the block identifier and the hash, and is signed using a second digital signature algorithm, which, in some embodiments, is different from the first digital signature algorithm. Integrity and origin authenticity of the signed block value are verified by verifying the digital signature of the first cryptographic message. Additionally, to verify the block value, a verification hash is computed on the signed block value of the block of the blockchain, and the verification circuit verifies that the hash from the cryptographic message matches the verification hash.

Abstract: A method of producing a lenticular device for an autostereoscopic display apparatus includes providing a substrate having a surface which corresponds in shape to a desired surface profile for the array of lenticular elements, and providing an optical layer mixture of an optically birefringent material and a polymer precursor over the substrate surface. The optical layer is exposed to a stimulus for polymerizing the polymer precursor to have at least a polymer surface layer, thereby enclosing the material between the polymerized material and the surface to define lenticular elements. This method allows a simple polymerization process, forming a single layer, to complete the LC cell formation in the desired lenticular array shape.
