Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G

Claim 6:
7. A secure computation method,
wherein [μ] is a secret share value of μ, a is a real number, m0 and m1 are multipliers of real numbers, and c is a value of 0 or 1 indicating a condition, the secure computation method, performed by processing circuitry, comprising:
obtaining [m0a] and [m1a] through secure computation using a secret share value [a] and the multipliers m0 and m1; and
obtaining and outputting a secret share value [c?m0a:m1a] of mea through secure computation using secret share values [c], [m0a], and [m1a], wherein the secret share value [c?m0a:m1a] is stored in a register of the processing circuitry and the secure computation is used in machine learning or data mining.
