Method and apparatus for managing spam message in messaging service
A method and apparatus for managing a spam message in a messaging service are disclosed. When a user reports a message determined as a spam message, he may directly select a sharing level of his personal information in order to prevent a leakage of the personal information according to a sharing policy, reports the spam message by transmitting only a hash value of the spam message in order to prevent an increase in traffic. With respect to reported spam messages, a user can access a spam server to check an errononeously reported message through a sorting algorithm.
1. A method for managing spam information by a terminal, the method comprising:
whenever a sharing policy of the spam information is received from a spam server, storing the sharing policy in the terminal;
informing a user about the latest sharing policy among the stored sharing policies, and inquiring of the user about whether to select alteration of a sharing extent indicating with whom personal information of the user reporting at least one spam message to the spam server is shared or an exposure degree indicating which portion of the personal information is shared;
transmitting an altered sharing policy which is altered according to a user selection to the spam server and storing the altered sharing policy in the terminal, wherein the altered sharing policy includes an altered sharing extent or exposure degree for the personal information of the user; and
transmitting the personal information of the user with an indicator specifying the altered sharing extent or exposure degree to the spam server after a corresponding spam report or subsequent spam report,
wherein the transmitted personal information is transferred by the spam server to other entities including spam servers according to the altered sharing extent or exposure degree, and
the indicator is used by the spam server to classify terminals which transmit an identical indicator in a group for managing the terminals.
2. The method of claim 1 , further comprising:
before the sharing policy is stored in the terminal, checking whether or not the spam server can be acceptable by the terminal through an electronic signature or H MAC information.
3. The method of claim 1 , wherein the indicator is defined according to a Table as follows:
indicator:
description:
0001
all of the personal information is shared with a
government agency and all companies
operating spam servers,
0002
only a phone number or an e-mail address is
shared with a government agency and all
companies operating spam servers,
0003
all of the personal information is shared
anonymously with a government agency and
all companies operating spam servers,
0004
all of the personal information is shared only
with a government agency,
0005
only a phone number or an e-mail address is
shared with a government agency, or
0006
all of the personal information is shared
anonymously only with a government agency.
4. A terminal for reporting spam information, the terminal comprising:
a receiver configured to receive a sharing policy of the spam information from a spam server;
a storage medium configured to store the received sharing policy and store an altered sharing policy according to a user selection;
a processor configured to inform a user about the latest sharing policy among the stored sharing policies, inquire of the user about whether to select alternation of a sharing extend indicating with whom personal information of the user reporting at least one spam message to the spam server is shared or an exposure degree indicating which portion of the personal information is shared for personal information of the user reporting at least one spam message to the spam server, and alter the sharing policy according to the user selection; and
a transmitter configured to transmit an altered sharing policy to the spam server, wherein the altered sharing policy includes an altered sharing extent or exposure degree for the personal information of the user, and transmit the personal information of the user with an indicator specifying the altered sharing extent or exposure degree to the spam server after a corresponding spam report or subsequent spam report,
wherein the transmitted personal information is transferred by the spam server to other entities including spam servers according to the altered sharing extent or exposure degree, and
the indicator is used by the spam server to classify terminals which transmit an identical indicator in a group for managing the terminals, and
wherein the sharing policy is for sharing information on spam messages between spam servers including the spam server, the spam messages are collected from each of the spam servers.
5. The terminal of claim 4 , further comprising:
a converter configured to perform a hash function for extracting a hash value from original text of the message.
6. The terminal of claim 4 , wherein the indicator is defined according to a Table as follows:
indicator:
description:
0001
all of the personal information is shared with a
government agency and all companies
operating spam servers,
0002
only a phone number or an e-mail address is
shared with a government agency and all
companies operating spam servers,
0003
all of the personal information is shared
anonymously with a government agency and
all companies operating spam servers, or
0004
all of the personal information is shared only
with a government agency.
