An authenticating method for sharing personal contents with at least one acquaintance by using a display apparatus capable of accessing a server through a network, the method comprising:

• if the display apparatus begins a first operation and is connected to the network, requesting contact details of a user of the display apparatus;
• if the contact detail information of the user is input, providing the contact detail information of the user to the server;
• if a message from the server confirming permission of sharing personal contents in relation to the user is received, requesting input of contact detail information of the at least one acquaintance of the user;
• if the contact detail information of the at least one acquaintance is input, providing the contact detail information of the at least one acquaintance to the server;
• and
• if acquaintance list information on acquaintances permitting sharing of personal contents from the server is received, setting the received acquaintance list information as acquaintance list information of the display apparatus user.

An authenticating method for sharing personal contents with at least one acquaintance by using a server capable of accessing at least one display apparatus through a network, the method comprising:

• if contact detail information is received from the at least one display apparatus, the server confirming to a display apparatus user whether or not sharing of personal contents is permitted, by using an automatic response system;
• if the display apparatus user permits sharing of the personal contents, transmitting a message confirming permission of sharing the personal contents to the display apparatus user, and registering the contact detail information of the display apparatus user and unique identification information of the at least one display apparatus;
• if contact detail information of the at least one acquaintance of the display apparatus user is received, by using the automatic response system, in relation to each acquaintance based on the received contact detail information of the at least one acquaintance, confirming whether or not sharing of the personal contents is permitted;
• and
• registering an acquaintance list, including information on acquaintances permitted to share the personal contents, as an acquaintance list of the display apparatus user and providing the acquaintance list information of the display apparatus user to the at least one display apparatus,
• wherein the server registers the contact detail information of the display apparatus user, the unique identification information of the at least one display apparatus, and the acquaintance list of the at least one display apparatus such that the contact detail information, the unique identification information and the acquaintance list are capable of referring to each other.

A display apparatus capable of accessing a server through a network, the apparatus comprising:

• a transmission and reception unit communicating data with the server through the network;
• a storage unit storing personal contents in relation to each acquaintance;
• an input unit inputting commands of at least one of a user and information;
• a control unit, wherein if at least one personal content of at least one acquaintance is received through the transmission and reception unit, performing control so that the received personal contents are stored in relation to each acquaintance in the storage unit, and if the at least one personal content of the at least one acquaintance is requested by the input unit, performing control so that the at least one personal content of the at least one acquaintance stored in the storage unit is output;
• and
• a display unit displaying the at least one personal content output from the storage unit.

• a transmission and reception unit communicating data with the server through the network;
• a storage unit storing personal contents and meta data corresponding to the personal contents in relation to each acquaintance;
• an input unit inputting commands of a user and information;
• a control unit, wherein if at least one personal content of at least one acquaintance and the meta data corresponding to the personal content are received through the transmission and reception unit, performing control so that the received personal content and the meta data corresponding to the personal content are stored in the storage unit, and if the at least one personal content of the at least one acquaintance is requested by the input unit, performing control so that the at least one personal content of the at least one acquaintance stored in the storage unit is output;
• and
• a display unit displaying the at least one personal content output from the storage unit.

A server capable of accessing at least one display apparatus through a network, the server comprising:

• a transmission and reception unit capable of communicating data with at least one display apparatus;
• a first storage unit storing unique identification information of the at least one display apparatus, contact details of a display apparatus user, and an acquaintance list;
• a second storage unit storing personal contents of a predetermined person;
• and
• a control unit requesting the personal contents of the predetermined person through the transmission and reception unit to a display apparatus storing the personal contents of the predetermined person, based on the acquaintance list and the unique identification information stored in the first storage unit, and if the personal contents of the predetermined person are received through the transmission and reception unit, examining whether or not there are personal contents different from the received personal contents among the personal contents stored in the second storage unit, and if it is determined that there are different personal contents, performing control so that the different personal contents are transmitted to the at least one display apparatus through the transmission and reception unit.
