摘要:
Using a mobile terminal while moving, a user has a voice conversation with a security terminal provided by a security service provider. This conversation creates a situation in which it is possible to immediately send an alarm if an emergency occurs, thus repelling assaulters or abductors lurking near the user. The mobile terminal is provided with GPS or the like, and position information of the mobile terminal is sent to the security terminal. The security service provider takes advertisements from advertisers selling goods or services, and prepares conversation scenarios that are the content of the conversations for automatic response based on those advertisements. The security terminal firstly provides the user with a voice conversation partner proxy service based on the conversation scenarios and secondly detects emergencies by detecting emergency messages from the mobile terminal or detecting the interruption of the conversation. After that, the security service provider can restrict the danger to the user to a minimum by undertaking emergency measures such as dispatching someone to the location where the mobile terminal is located.

The present invention provides a technique which makes it possible to eliminate unauthorized playback of contents where unauthorized apparatuses are used and enable only authorized playback apparatuses to play back contents properly. The playback apparatus of the present invention obtains encrypted key information that has been encrypted by a first secret-key encrypting method, and decrypt the encrypted key information into key information using a secret key stored in a storing unit. When the key information is key-updating information, the playback apparatus updates the secret key according to the key-updating information. When the key information is a decryption key, the playback apparatus (i) obtains an encrypted content key that has been encrypted by a second secret-key encrypting method, (ii) decrypts the encrypted content key into a content key using the decryption key, (iii) obtains a scrambled content that has been scrambled by a scramble encrypting method, (iv) descramble the scrambled content using the decrypted content key, and (v) plays back the descrambled content.
摘要:
According to a typical invention of the inventions disclosed in the present application, a semiconductor chip with an electronic circuit formed therein is fixed to a die pad for a lead frame having projections formed on the back thereof, with an organic dies bonding agent. Pads on the semiconductor chip, and inner leads are respectively electrically connected to one another by metal thin lines. These portions are sealed with a molding resin. Further, each inner lead extends to the outside of the molding resin and is processed into gull-wing form for substrate mounting. Moreover, the inner lead is processed by soldering so that an external terminal is formed. Thus, since the projections are provided on the back of the die pad, the back of a packing material is brought into point contact with that of the die pad as compared with the conventional face-to-face contact. It is therefore possible to minimize the transfer of organic substances from the packing material. Further, since such transfer that a reduction in adhesive property occurs in the back of the die pad, is greatly reduced, the adhesiveness between the upper surface of the die pad and the molding resin is improved, whereby the resistance of SMD to the reflow is enhanced.
