Abstract
An electronic apparatus is disclosed. The apparatus includes: a memory storing instructions; a communication interface; and at least one processor including processing circuitry, wherein the at least one processor is configured to obtain a plurality of user data and a plurality of verification random data by replicating user data and verification random data into the plurality of user data and the plurality of verification random data, respectively, when the user data is obtained, obtain a plurality of ciphertext sets by encrypting the plurality of user data and the plurality of verification random data, respectively, under different secret keys, and control the communication interface to transmit the plurality of ciphertext sets to a server.
Claims17
An electronic apparatus comprising:
- a memory storing instructions;
- a communication interface;
- and
- at least one processor including processing circuitry,
- wherein the at least one processor is configured to
- obtain a plurality of user data and a plurality of verification random data by replicating user data and verification random data into the plurality of user data and the plurality of verification random data, respectively, when the user data is obtained,
- obtain a plurality of ciphertext sets by encrypting the plurality of user data and the plurality of verification random data, respectively, under different secret keys, and
- control the communication interface to transmit the plurality of ciphertext sets to a server.
A control method of an electronic apparatus, the method comprising:
- obtaining a plurality of user data and a plurality of verification random data by replicating user data and verification random data into the plurality of user data and the plurality of verification random data, respectively, when the user data is obtained;
- obtaining a plurality of ciphertext sets by encrypting the plurality of user data and the plurality of verification random data, respectively, under different secret keys;
- and
- transmitting the plurality of ciphertext sets to a server.
A non-transitory computer-readable recording medium storing a program for executing a method for operating an electronic apparatus, wherein the method includes
- obtaining a plurality of user data and a plurality of verification random data by replicating user data and verification random data into the plurality of user data and the plurality of verification random data, respectively, when the user data is obtained,
- obtaining a plurality of ciphertext sets by encrypting the plurality of user data and the plurality of verification random data, respectively, under different secret keys, and
- transmitting the plurality of ciphertext sets to a server.
