Mobile data memory with automatic delete function

Abstract

The invention relates to a mobile data memory (1) comprising a data memory module (2) and a holding and / or carrying device (3), wherein the data memory module (2) has a non-volatile, re-writable semiconductor memory (4) and an access controller (5) with a communications module (7), wherein furthermore the communications module (7) is connected to a communications interface (8). The holding and / or carrying device (3) has a contact detection unit (16); the data memory module (2) furthermore has an allocation monitoring module (6) which is designed to evaluate the contact detection unit (16) and which is connected to the semiconductor memory (4) and / or to the access controller (5). The invention further relates to a method for person-based saving of information in a mobile data memory, wherein a remote communications station can access information saved in the data memory via a communications interface, and wherein a loss of the allocation of the mobile data memory to a person is detected. The data memory is deleted as soon as it is removed from the holding and / or carrying device.

Description

technical field [0001] The invention relates to a removable data memory, comprising a data storage module and a fixing or supporting device, wherein the data storage module has a non-volatile, rewritable semiconductor memory and an access control device with a communication module, wherein the communication module is also connected to a communication interface . Background technique [0002] The prior art discloses a wide variety of removable data storage devices, most of which are designed as non-volatile semiconductor storage devices and can be easily removed due to their compact arrangement within a housing. For example, so-called USB sticks are known, in which a non-volatile semiconductor memory is accommodated in a housing and can be connected to a data processing device via a serial communication interface. Such data storage devices are usually carried with them, for example by placing them in a receptacle for clothing. However, this carry-on approach also carries th...

A disadvantage of the known device is, inter alia, that the information remains in the storage unit until a subsequent access step of checking the correspondence with the user

In particular, there is a danger that removable data storage can be read out intentionally for misuse, for example by disabling or circumventing existing security mechanisms, by directly reading the storage device
