A method of managing an image by an electronic device may include: generating a first encryption image by encrypting a first image; acquiring bitstream data corresponding to a second image related to the first image; generating a changed image by combining at least some of the bitstream data and the first encryption image; and transmitting the changed image to an external electronic device.

Electronic device and method of managing image by electronic device

Apparatuses are provided for connecting electronic devices. An apparatus includes short-range communication circuitry; a communication software module; and a processor adapted to connect with a wireless access point (AP); broadcast, using the short-range communication circuitry, a request message to perform a service associated with file sharing or conferencing, the request message including a unique identifier or a unique name related to the service; receive, via the wireless AP, a response message from at least one external device connected with the wireless AP; establish a communicative connection with the at least one external device via the wireless AP; and perform, using the communication software module, an operation for the service with the at least one external device.

Method for connection between electronic devices and electronic device thereof

Methods and apparatuses are provided for connecting electronic devices. A first electronic device broadcasts a message including at least one of related service information and connectivity information necessary for accessing a wireless access point (AP) accessed by the first electronic device, by using short-range communication. The first electronic device receives a connection request from at least one second electronic device via the wireless AP.

Provided is an apparatus and method for managing Digital Rights Management (DRM) contents in a portable terminal. The method includes when a license of the DRM content is consumed, changing license information, which is stored in an external memory, on the DRM content; storing information relating to changed data of the external memory into an internal memory; determining whether the changed license information stored in the external memory has changed by using the information stored in the internal memory when the DRM content is used; and determining whether the DRM content is available according to whether the changed license information has changed.
