Server, method for controlling server, and terminal device

A method and device for securing data of a message is provided. A method for encrypting a message of a user terminal device includes: receiving a message via a message input window; displaying the received message; encrypting the message by using a key index and an encryption key corresponding to a chatting window for the message based on an instruction for transmitting the message to another chatting party being received; and transmitting the encrypted message to the other chatting party.

Method and terminal device for encrypting message

A user terminal device is provided. The user terminal device includes: a communicator; a display; and a processor configured to receive a message from another electronic device through the communicator, control the display to display the received message, and based on the received message being a multimedia message including at least one of an image, a sound, and a video by analyzing the received message, control the display to display a recommended response list based on at least one of an age or a gender of the user of the terminal corresponding to a type of content included in a multimedia message. Therefore, convenience of a user using the user terminal device is improved.

User terminal device for recommending response to a multimedia message based on age or gender, and method therefor

The present invention relates to a method for protecting content of an electronic device, comprising the steps of: enabling a first security module to transmit a data encryption request to a second security module when data requiring security is generated according to the execution of a security application by the first security module in a security storage region of a memory; enabling the second security module to generate an encryption key by using the authentication information included in the data encryption request and to encrypt the data included in the data encryption request by using the encryption key; enabling the second security module to transfer the encrypted data to the first security module; and enabling the first security module to store the encrypted data in the security application.

Method and apparatus for protecting application

A method of controlling transmission of content data includes establishing a communication channel with an external device; transmitting the content data through the communication channel to the external device; verifying a plurality of times whether the content data is transmitted to the external device within an acceptable transmission range to generate a verification result; and determining whether to continue transmitting the content data according to the verification result. The verification is periodically performed according to an amount of the content data to be transmitted.

Method and apparatus for controlling transmission of content data

An electronic device is disclosed. The electronic device which is included in a home network, the device includes a sensor, a communicator comprising communication circuitry configured to communicate with an external device which is included in the home network, and a processor configured to control the communication circuitry, to encrypt first data which is initially acquired from the sensor with a first encryption algorithm and transmit the encrypted standard data to the external device, determine third data based on the first data and a second data in response to the second data being acquired from the sensor after the first data is acquired, to encrypt the third data with a second encryption algorithm and to transmit the encrypted third data to the external device.

Electronic device, communication method and encrypting method thereof

A computing system including a memory that is shared by a plurality of components of the computing system in order to exchange data between the plurality of components; and a controller configured to control the plurality of components to encrypt the data and to record the encrypted data in the memory.

Computing system and method of operating computing system

Provided are a method and apparatus for controlling transmission of content data. In the method, a communication channel is initially established to transmit the content data, the content data is transmitted through the established communication channel, verification is performed a plurality of times to determine whether the content data is transmitted within an acceptable transmission range, and whether to continue the transmission of the content data is determined according to the verification result. Accordingly, when a client moves to a location outside a predetermined acceptable transmission range in a wireless environment, a server stops transmission of the content data. In addition, content data can be continuously transmitted regardless of interference caused by a temporary obstacle between a server and a client.

Watermarking method and apparatus for tracking hacking and method and apparatus for blocking hacking of content are provided. The watermarking method includes: obtaining device information from a reception device, with which content is shared, through a determined network channel; generating watermark data based on the obtained device information; and generating watermarked multimedia content by inserting the generated watermark data into content. The method of blocking hacking of content includes: if hacked content is found, detecting watermark data from the hacked content; detecting transmission and reception device information from the detected watermark data; and extracting a progress route of the content based on the detected transmission and reception device information and performing revocation on a hacked device.

Watermarking method and apparatus for tracking hacked content and method and apparatus for blocking hacking of content using the same

A method and apparatus for detecting a leak of an information resource of a device. Source code is obtained from an application and is analyzed to determine whether at least one information resource from among information resources of a device is transmittable to outside the device by tracking a task performed on the at least one information resource, thereby detecting whether the application is externally leaking an information resource from the device.

Method and apparatus for detecting leak of information resource of device

Provided are a method and apparatus for effectively fixing scrambled content. The method includes checking fixing information for a program map table (PMT) packet of packets constituting the content, the fixing information being used to fix a transformed part of the content; extracting location information of a next PMT packet containing fixing data for fixing the transformed part of the content from the fixing information of the PMT packet; and fixing the transformed part of the content by using the fixing data in the next PMT packet indicated by the extracted location information. Accordingly, it is possible to easily detect a location of the content, which stores the fixing information, thereby expediting fixing of the transformed content.

Method and apparatus for efficiently fixing transformed part of content

Provided are methods of generating and verifying an electronic signature of software data, wherein software data is split into a plurality of blocks, electronic signatures corresponding to each of the blocks are generated, and some of the electronic signatures are randomly selected for verification.
