Method and system for handling a defective electronic user terminal
First Claim
1. A system for handling an at least supposedly partially defective electronic user terminal comprising functionally-relevant circuits and at least one security-relevant circuit located within or connected to the electronic user terminal, wherein the security-relevant circuit is electronically connected to the electronic user terminal, wherein the electronic user terminal, after being successfully identified by a server, is automatically and irreversibly put into an irreparable state by way of an irreversible manipulation of at least one component of the user terminal, if a performed diagnosis of the functionally-relevant circuits of the user terminal indicates that these functionally-relevant circuits are impaired in terms of their functionality or have failed,the electronic user terminal establishes directly or indirectly a data connection between the user terminal and the server and the security-relevant circuit transmits a unique identifier of the user terminal for the identification thereof to the server, even if a power supply of the electronic user terminal or functionally-relevant circuits of the user terminal fail, and wherein, after receipt of a confirmation to render the user terminal unusable, the server causes the security-relevant circuit of the user terminal to effect the irreversible manipulation of at least one component of the user terminal by sending a control command to the security-relevant circuit to put the user terminal into an irreparable state.

Abstract
The invention relates to a system for handling an at least supposedly partially defective electronic user terminal, wherein the electronic user terminal, after being successfully identified by a server, is automatically and irreversibly put into an irreparable state if a performed diagnosis of functionally relevant circuits of the user terminal indicates that said functionally relevant circuits are impaired in the functional capability thereof or have failed.

1. A system for handling an at least supposedly partially defective electronic user terminal comprising functionally-relevant circuits and at least one security-relevant circuit located within or connected to the electronic user terminal, wherein the security-relevant circuit is electronically connected to the electronic user terminal, wherein the electronic user terminal, after being successfully identified by a server, is automatically and irreversibly put into an irreparable state by way of an irreversible manipulation of at least one component of the user terminal, if a performed diagnosis of the functionally-relevant circuits of the user terminal indicates that these functionally-relevant circuits are impaired in terms of their functionality or have failed,
the electronic user terminal establishes directly or indirectly a data connection between the user terminal and the server and the security-relevant circuit transmits a unique identifier of the user terminal for the identification thereof to the server, even if a power supply of the electronic user terminal or functionally-relevant circuits of the user terminal fail, and wherein, after receipt of a confirmation to render the user terminal unusable, the server causes the security-relevant circuit of the user terminal to effect the irreversible manipulation of at least one component of the user terminal by sending a control command to the security-relevant circuit to put the user terminal into an irreparable state.

15. A method for handling an at least partially defective electronic user terminal comprising functionally-relevant circuits and at least one security-relevant circuit located within or connected to the electronic user terminal, wherein the security-relevant circuit is electronically connected to the electronic user terminal,
wherein the electronic user terminal, after being successfully identified by a server, is automatically and irreversibly put into an irreparable state by way of an irreversible manipulation of at least one component of the user terminal, if a performed diagnosis of functionally-relevant circuits of the user terminal indicates that these functionally-relevant circuits are impaired in terms of their functionality or have failed, the electronic user terminal establishes directly or indirectly a data connection between the user terminal and the server and the security-relevant circuit transmits a unique identifier of the user terminal for the identification thereof to the server, even if a power supply of the electronic user terminal or functionally-relevant circuits of the user terminal fail, and wherein, after receipt of a confirmation to render the user terminal unusable, the server causes the security-relevant circuit of the user terminal to effect the irreversible manipulation of at least one component of the user terminal by sending a control command to the security-relevant circuit to put the user terminal into an irreparable state.

16. An electronic user terminal having functionally-relevant circuits and having at least one security-relevant circuit located within or connected to the electronic user terminal, wherein the security-relevant circuit is electronically connected to the electronic user terminal,
wherein the electronic user terminal, after being successfully identified to a server is automatically put into an irreparable state by the server by way of an irreversible manipulation of at least one component of the user terminal, if a performed diagnosis of functionally-relevant circuits of the user terminal indicates that these functionally-relevant circuits are impaired in terms of their functionality or have failed, the electronic user terminal establishes directly or indirectly a data connection between the user terminal and the server and the security-relevant circuit transmits a unique identifier of the user terminal for the identification thereof to the server, even if a power supply of the electronic user terminal or functionally-relevant circuits of the user terminal fail, and wherein, after receipt of a confirmation to render the user terminal unusable, the server causes the security-relevant circuit of the user terminal to effect the irreversible manipulation of at least one component of the user terminal.

17. A server for handling an at least partially defective electronic user terminal,
wherein after the electronic user terminal has established directly or indirectly a data connection between the user terminal and the server and after the user terminal has been successfully identified by the server by examining an identifier received from a security-relevant circuit of the user terminal via the established data connection, wherein the security-relevant circuit is electronically connected to the electronic user terminal, the server initiates the process of putting the electronic user terminal into an irreparable state by way of an irreversible manipulation of at least one component of the user terminal by sending a control command, if a performed diagnosis of functionally-relevant circuits of the user terminal indicates that these functionally-relevant circuits are impaired in terms of their functionality or have failed.
