Disclosed is an encryption method and apparatus. The encryption method using homomorphic encryption may include generating a ciphertext by encrypting data, and bootstrapping the ciphertext by performing a modular reduction based on a selection of one or more target points for a modulus corresponding to the ciphertext.

Encryption method and apparatus using homomorphic encryption

Disclosed is an electronic apparatus. The electronic apparatus includes a memory storing a composite function in which at least two polynomials are composed and a processor configured to, based on a comparison operation command being received for a plurality of homomorphic ciphertexts, perform operation by reflecting the plurality of homomorphic ciphertexts to the composite function, and obtain a comparison result of the plurality of homomorphic ciphertexts based on the operation result, each of the at least two polynomials may output a value in a preset range for a value in a preset domain, and a domain of one of the at least two polynomials may be determined based on a range of a previous polynomial.

Electronic apparatus, control method thereof and server

An encryption method and apparatus based on homomorphic encryption using an odd function property. The encryption method includes generating a ciphertext by encrypting data, and bootstrapping the ciphertext by performing a modular reduction based on an odd function property for a modulus corresponding to the ciphertext.

Encryption method and apparatus based on homomorphic encryption using composition of functions

A mobile terminal includes: a body including a first body, a second body, and a connection unit configured to connect the first and second bodies to each other so that an angle between the first and second bodies is changeable, and the body formed so that at least one region thereof is formed of a transmissive region; a transparent flexible display unit mounted to one surface of the body, and configured to output screen information; a sensing unit configured to sense a first state where the flexible display unit is unfolded, and a second state where the first and second bodies are overlapped with each other, by change of the angle; and a controller configured to change transparency of a region corresponding to the transmissive region, based on change of the angle.

Mobile terminal

Mobile phone

According to one embodiment of the present invention, a mobile terminal includes a touchscreen configured to display a list including a plurality of categories and at least one content grouped for each of the plurality of categories, and a controller, if a command for a reduced display of the list is received, configured to generate summary information for each of the plurality of categories based on information of the grouped at least one content, to hide the grouped at least one content from the list, and then to control the touchscreen to display the plurality of categories and the generated summary information corresponding to the plurality of categories.

Mobile terminal and controlling method thereof

Disclosed herein are a mobile terminal and a method for controlling the same, which provide a user with a frame-scale content playback progress status information from the related art time-scale content playback progress status information. As described above, the mobile terminal includes a touch screen configured to display a playback screen of a content including image, and a controller controlling operations associated to a playback of the content. Herein, the controller may detect whether or not a command for displaying a playback progress status of the content in one of a time scale and a frame scale is being inputted. And, when the command is inputted, the controller may switch and display the playback progress status of the content from the time scale to the frame scale, and vice versa.
