A method, corresponding control logic, and a correspond system for detecting a virtual storage volume. The method includes: determining a first access pattern for a read operation of a target storage volume; monitoring a second access pattern of at least one other storage volume of a computer system during the read operation; determining a correlation between the first access pattern and the second access pattern; and deriving that the target storage volume is a virtual storage volume if the determined correlation is above a predefined threshold.

Method, control logic and system for detecting a virtual storage volume and data carrier

A record carrier for storing at least one stream of linked content cells thereon, which linking is performed based on navigation data. The record carrier includes modified navigation data and/or a stream arrangement of at least one stream of linked content cells, so that an access of the at least one stream of linked content cells on the record carrier under consideration of the navigation data is not disturbed, whereas a generally linear access of the at least one stream of linked content cells on the record carrier is disturbed.

DVD copy protection

A method and system for managing access to add-on data files having an add-on data file attribute, which is used by a software application. The method: monitors input/output commands of the software application to an application programming interface of a code layer to determine whether an access to a data file with the add-on data file attribute is requested by the software application; checks whether an access code for the add-on data file is present in an access code list related to the software application if at least one of the monitored input/output commands request access to the add-on data file, if the access code is not present in the access control list; retrieves the access code from an external source outside of the access control list; and provides access to the add-on data file if the access code is present.

Method and system for managing access to add-on data files

The invention relates to a memory authentication method based on a pattern of storage areas of said memory that have altered latencies that are respectively altered such that the respective alteration of the latency of a storage area lies within a measurement noise of latency measurements in respect to the standard latency of said storage area when the measurement is performed with a reading device for accessing said record medium. The verification is then performed by a correlation of the latencies of the altered storage areas with a key used to alter the storage areas.

Disc signature for disc authentication

A method for generating printing data on the basis of which a disk label is creatable includes the steps of a) generating graphic data representing said disk label at a graphic data generating location (to), b) transforming said graphic data into said printing data at a printing data generating location (to), wherein said graphic data generating location (to) and said printing data generating location (to) are parts of a communication network (), respectively, wherein steps a) and b) are controlled by a network capable client (to) being part of said communication network ().

Method for generating disk label print data

Latency information is used for coding of additional information in a record medium. This additional information which gets embossed in the record medium might be used for verification purposes in that only storage media with the correct latency information are judged to be authentic or might be decoded in a proper way. This technique is applicable to record media, recordable record media, an emulator for recordable or non-recordable record media, a method for producing recordable or non-recordable record media, a method for verifying recordable or non-recordable record media, a record medium writing device for producing recordable or non-recordable record media, and a record medium accessing device for verifying recordable or non-recordable record media.
