摘要:
The present invention relates to a drive device and method of reading from or writing to a record carrier (10), wherein a predetermined portion of the maximum storage capacity of said record carrier (10) is exposed via an access interface function of a drive device (30). At least one of a size and a location of the predetermined portion is selectable by an input function at the interface function. Thereby, legacy host devices which cannot use the full storage capacity of advanced drive devices (30) can take full or better advantage of the total storage capacity.
摘要:
A device (1; 1′) or an application (3) may be activated by supplying a series of activation codes. The device checks whether each code is received in a predetermined order and within a certain time period. If the check fails, the device or the application may be terminated. The codes may be stored on tokens (2), such as cards or optical information carriers. The device or the application may be a toy, such as a virtual or mechanical pet.
摘要:
There is described a personal communication apparatus (10), for example a mobile telephone, for generating a verifiable recording of a transaction (240), the transaction (240) comprising an exchange of information. The apparatus includes a receiving component, a protection component, a memory and a recording component. The receiving component is capable of receiving a transaction between a user (100) of the apparatus and a remote person, and of receiving biometric data (BIOKY) of the remote person. The protection component is capable of protecting the voice conversation with the biometric data (BIOKY). The recording component is capable of recording the transaction protected with the biometric data on the memory (30). There is also described a communication apparatus (10), which may be the same mobile telephone, operable to support authentication of a transaction therein. The communication apparatus comprises a memory (30) and an authentication component. The authentication component is capable of providing access to a protected transaction stored on the memory if biometric data (BIOKY) measured by a biometric measuring means (80) corresponds to earlier biometric data (BIOKY) used to protect the voice conversation (240).
摘要:
There is described a communication apparatus (10) for communicating via one or more services provided by a service provider (80). The apparatus (10) is preferably a mobile telephone. Moreover, the apparatus (10) includes a memory device (30) susceptible to receive one or more data carriers (20) distributed by the provider (80) in return for payment. The device (30) is operable on presentation of the one or more data carriers (20) thereto to directly access data (60, 65, 300) on the one or more data carriers (20). Furthermore, the apparatus (10) is further arranged to be capable of communicating the data (60) to the provider (80) for the provider (80) to check the data (60) for updating a toll credit for the apparatus (10) according to information conveyed in the data (60) when the data (60) is found to be valid. Use of the data carrier (20) enables advertising and addresses problems encountered when, for example, using contemporary scratch cards for toll crediting purposes.
摘要:
In the method of the invention, a request for a digital right to an encrypted content item is transmitted to a server (61). The request contains a circuit identifier identifying an integrated circuit and a content identifier identifying the encrypted content. Subsequently, an encrypted digital right, being encrypted by using a public key associated 5 with the integrated circuit, is received from the server (61). Furthermore, the integrated circuit is instructed to decrypt the encrypted digital right by using a private key associated with the integrated circuit and to store the digital right in the integrated circuit. The private key is being stored in the integrated circuit. The system of the invention contains a client (63) performing the method and a server (61) as referred to in the method. The electronic device 10 performs the method of the invention.
摘要:
According to a first aspect of the invention, data that will be needed for starting the applications of the storage medium are stored in a reserved area of the storage medium. The data stored in the reserved area are read and cached in a single operation when the storage medium is declared to the operating system. Therefore the seeking and spinning-up operations of the reading head that are required for starting the application(s) are limited to a minimum. According to a second aspect of the invention, programs that create a new application file indicate whether this application file should be assigned to the reserved area. If so, the file system implementation allocates the application file to the reserved area.
摘要:
The present invention relates to methods and a system for managing digital rights. The invention is based on the idea that a digital voucher (100) is provided with access control information for accessing digital content located on a server (104) of a content provider. A consumer of the digital content reads the voucher (100) by means of a bar code reader, an RF detector (102) or the like. This 104 reading means (102) is connected to some computing means (103) such as a computer, a mobile phone, a PDA, a set-top box etc. The computing means (103) transfers the access control information to a server (104) of a content provider. The server (104) to which the access control information is transferred processes the access control information, and depending on the result of the processing, the computing means (103) is given different levels of access to digital content located on the server (104).
摘要:
The present invention relates to a storage device, a storing method and rewritable record carrier for storing data file, wherein a rewriting frequency of the date files is identified and the data files are classified based on their identified rewriting frequency. Each data file is then written using a rule selected according to the result of classification. The definition of the allocation class and rules based on the rewriting frequency enables an optimization of the file storage for endurance and power consumption. Thereby, the life time of the storage medium and the battery life of the whole system can be extended.
