August 12, 2014



By a News Reporter-Staff News Editor at Information Technology Newsweekly -- According to news reporting originating from Alexandria, Virginia, by VerticalNews journalists, a patent by the inventor Ge, Ping (New Taipei, TW), filed on September 28, 2011, was published online on July 29, 2014.

The assignee for this patent, patent number 8793484, is Wistron Corporation (Hsichih, New Taipei, TW).

Reporters obtained the following quote from the background information supplied by the inventors: "The present invention relates to an electronic device with an encryption function and a message encryption method, and more specifically, to an electronic device capable of encrypting and then storing a received or sent message and a message encryption method.

"With development of technology, electronic devices are widely used in daily life, such as a mobile phone, a PDA (Personal Digital Assistant), or a tablet computer. In general, most electronic devices allow different users to send messages to each other via SMS (Short Message Service), MMS (Multimedia Message Service), an e-mail service, or other message service.

"Inevitably, an electronic device owned by a user may be lent to another person. When the electronic device is lent to another person, this person may possibly view private messages stored in the electronic device. Furthermore, if a message or an e-mail is sent to the electronic device suddenly during this person utilizes the electronic device, this person may also view the message or the e-mail by accident. In other words, when the electronic device is lent to another person, the owner of the electronic device can not prevent received or stored messages in the electronic device from being viewed by this person. This problem may cause the owner of the electronic device much trouble."

In addition to obtaining background information on this patent, VerticalNews editors also obtained the inventor's summary information for this patent: "The present invention provides an electronic device with a message encryption function. The electronic device includes a configure interface module, a storage module, an encryption module, and a message processing module. The configure interface module is used for setting an encryption code. The message processing module is electrically connected to the configure interface module, the storage module and the encryption module for receiving or sending a message, accessing the encryption code from the configure interface module, and transmitting the message and the encryption code to the encryption module. The encryption module encrypts the message with the encryption code so as to generate an encrypted message and then transmits the encrypted message to the message processing module. The message processing module stores the encrypted message in the storage module.

"According to the claimed invention, the message processing module checks whether the encryption code exists when the message processing module receives or sends the message, and the message processing module triggers the configure interface module to set the encryption code if the encryption does not exist.

"According to the claimed invention, the message processing module accesses the encryption code from the configure interface module and transmits the encrypted message, a message type, and the encryption code to the encryption module when the message processing module reads the encrypted message from the storage module, the encryption module determines whether the encrypted message has been read or not, the encryption module decrypts the encrypted message with the encryption code to generate a decrypted message and then transmits the decrypted message to the message processing module if the encrypted message has been not read yet, and the encryption module directly transmits the encrypted message to the message processing module if the encrypted message has been read.

"According to the claimed invention, the electronic device further includes a display module electrically connected to the message processing module for displaying the encrypted message or the decrypted message.

"According to the claimed invention, the message processing module checks whether the encryption code has been set over a timeout time when the message processing module reads the encrypted message from the storage module, and the message processing module triggers the configure interface module to reset another encryption code if the encryption code has been set over the timeout time.

"According to the claimed invention, the message processing module checks whether the encrypted code exists if the encrypted code has been not set over the timeout time yet, and the message processing module triggers the configure module to set the encryption code if the encryption code does not exist.

"According to the claimed invention, the configure interface module includes a memory unit for storing the encryption code.

"The present invention further provides a message encryption method including setting an encryption code, receiving or sending a message, encrypting the message with the encryption code to generate an encrypted message, and storing the encrypted message.

"According to the claimed invention, the message encryption method further includes checking whether the encryption code exists when sending or receiving the message and setting the encryption code if the encryption code does not exist.

"According to the claimed invention, the message encryption method further includes reading the encrypted message, determining whether the encrypted message has been read or not according to a message type, decrypting the encrypted message with the encryption code to generate a decrypted message if the encrypted message has been not read yet, and not decrypting the encrypted message if the encrypted message has been read.

"According to the claimed invention, the message encryption method further includes checking whether the encryption code has been set over a timeout time when reading the encrypted message and resetting another encryption code if the encryption code has been set over the timeout time.

"According to the claimed invention, the message encryption method further includes checking whether the encryption code exists if the encryption code has been not set over the timeout time and setting the encryption code if the encryption code does not exist.

"These and other objectives of the present invention will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings."
