Biometric locking methods and systems for internet of things and the connected person

A method for configuring biometric access for a single user to a design, the method comprising:

• receiving a biometric template originating from the single user;
• obtaining a protected biometric template corresponding to the protected biometric template using a first SSG and first transformation parameters;
• providing the protected biometric template to a second SSG configured to use second transformation parameters to generate an obfuscation key;
• obfuscating the design based at least in part on receiving a bitstream representing obfuscated portions of the design, the bitstream generated from the obfuscation key.

An apparatus for configuring biometric access for a plurality of legitimate users to a design, wherein the apparatus comprises at least one processor and a memory comprising computer executable instructions, the memory and the computer executable instructions configured to, with the at least one processor, cause the apparatus to:

• receive a plurality of biometric templates, wherein each biometric template has originated from one of the plurality of legitimate users;
• obtain a protected biometric template for each of the plurality of biometric templates using a first secure sketch generator (SSG) and first transformation parameters;
• determine a common protected biometric template for the plurality of legitimate users based at least in part on combining a plurality of protected biometric templates using a Merkle tree and a corresponding index value for each of the plurality of legitimate users;
• cause the design to be obfuscated based at least in part on a common obfuscation key generated from the common protected biometric template using a second SSG and second transformation parameters, wherein the design is configured to be de-obfuscated for a given legitimate user responsive to biometric input from the given legitimate user.

A computer program product for configuring biometric access for a plurality of legitimate users to a design, the computer program product comprising at least one computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising executable portions configured to cause at least one processor to:

• receive a plurality of biometric templates, wherein each biometric template has originated from one of the plurality of legitimate users;
• obtain a protected biometric template for each of the plurality of biometric templates using a first secure sketch generator (SSG) and first transformation parameters;
• determine a common protected biometric template for the plurality of legitimate users based at least in part on combining a plurality of protected biometric templates using a Merkle tree and a corresponding index value for each of the plurality of legitimate users;
• cause the design to be obfuscated based at least in part on a common obfuscation key generated from the common protected biometric template using a second SSG and second transformation parameters, wherein the design is configured to be de-obfuscated for a given legitimate user responsive to biometric input from the given legitimate user.
