摘要： The present invention relates to contents sharing method and system using an external memory. A method for transmitting encrypted contents to an external memory device list includes receiving a device list and public keys for devices, encrypting a domain key by using a public key to generate at least one device domain key, and transmitting the device domain key to the external memory. The method for performing encrypted contents further includes checking a public key of a device, extracting a device domain key corresponding to a public key checked by at least one device domain key stored in an external memory, decoding the extracted device domain key, decoding the encrypted contents by using the decoded device domain key, and performing the decoded encrypted contents. According to the present invention, since a single piece of contents stored in an external memory is reproducible by a plurality of devices, the existing problem of repeatedly settling the single piece of contents is solved and external memory resources are efficiently used.

摘要： The present invention relates to a user created contents protection system and method. Copyright protection for protecting contents on user created contents is performed by using a contents upload server or a user terminal including a digital rights management (DRM) packager. Therefore, copyright protection of the user created contents is performed, and a user that legally provides user created contents can be rewarded. Also, when illegally distributed user created contents are generated, a person having initially attempted to distribute the contents is tracked to clarify responsibility.
