## Abstract

A removable communication card for mobile network devices, and respectively a corresponding authentication method applied therewith. The removable communication card includes an identification module for storing identification data for users, a measurement device for capturing a first biometric feature and a second biometric feature of a user, and an analysis module with a processor unit for comparison of the first and the second biometric features with the stored identification data for the user.

## Claims

### Claim 1

A removable communication card, comprising:
an identification module operable to store identification data for users in a network, the identification data having data for authentication of the users in the network;
a measurement device operable to capture a first and a second biometric feature of one user, the first biometric feature being different from the second biometric feature; and
an analysis module having a processor unit, the analysis module being operable to attempt verification of a match between the first and the second biometric features of the one user and the identification data to authenticate the one user, wherein:
the identification data comprises code for initialization of the identification data;
biometric data of the one user is assigned to the identification data, during the initialization of the identification data;
the measurement device captures the first biometric feature of the one user;
in a case where the analysis module verifies a match between the first biometric feature and the identification data, the one user is authenticated in the network using the identification data; and
in a case where the analysis module cannot verify a match between the first biometric feature and the identification data, the measurement device captures the second biometric feature of the one user and the analysis module verifies a match for the second biometric feature with the identification data, to authenticate the one user in the network using the identification data.

### Claim 2 (depends on 1)

The removable communication card according to claim 1, wherein the removable communication card is connected to a network device via a contact interface or via a contactless interface.

### Claim 3 (depends on 2)

The removable communication card according to claim 2, wherein the measurement device comprises a scanning unit configured to capture fingerprints, the scanning unit being installed such that when the contact interface is connected to the network device, the scanning unit captures fingerprints of the one user.

### Claim 4 (depends on 1)

The removable communication card according to claim 1, comprising connecting the removable communication card to a network device via a network interface module.

### Claim 5 (depends on 4)

The removable communication card according to claim 4, wherein the network interface module comprises an interface that is configured to connect to the network wirelessly and/or by a wire.

### Claim 6 (depends on 1)

The removable communication card according to claim 1, wherein the code is usable by the one user as a fallback and is entered by the one user via input elements of a network device connected to the removable communication card when the first biometric feature is not unambiguously assignable by the analysis module to the one user.

### Claim 7 (depends on 1)

The removable communication card according to claim 1, wherein the identification module comprises a Subscriber Identity Module (SIM) or a smart card.

### Claim 8 (depends on 1)

The removable communication card according to claim 1, wherein the authentication data of the users in the network comprises at least IMSI and/or MSISDN.

### Claim 9 (depends on 1)

The removable communication card according to claim 1, wherein the measurement device is integral with the identification module.

### Claim 10 (depends on 1)

The removable communication card according to claim 1, wherein the measurement device is configured to capture dynamic values of the one user.

### Claim 11 (depends on 10)

The removable communication card according to claim 10, wherein the dynamic values include movements of a finger of the one user.

### Claim 12 (depends on 1)

The removable communication card according to claim 1, wherein the removable communication card is a PC card or a PC1 card.

### Claim 13 (depends on 1)

The removable communication card according to claim 1, wherein the measurement device comprises sensors configured to capture one or more individual physical measurement values for the one user when the removable communication card is connected to a network device.

### Claim 14 (depends on 13)

The removable communication card according to claim 13, wherein the one or more individual physical measurement values include at least one of body temperature, blood pressure, pulse, and electric current on the body surface of the one user.

### Claim 15

A method, the method comprising:
in a removable communication card:
identifying one user;
assigning biometric data of the one user to stored identification data for the one user;
capturing a first biometric feature of the one user;
comparing the first biometric feature of the one user with the stored identification data for the one user;
authenticating the one user upon a successful matching of the first biometric feature of the one user with the stored identification data, in a network using the identification data;
capturing a second biometric feature of the one user upon an unsuccessful matching of the captured first biometric feature of the one user with the stored identification data, the second biometric feature being different from the captured first biometric feature;
comparing the second biometric feature of the one user with the stored biometric identification data; and
authenticating the one user upon a successful matching of the second biometric feature of the one user with the stored identification data, in the network using the identification data.

### Claim 16 (depends on 15)

The method according to claim 15, comprising capturing the first biometric feature and the second biometric feature of the one user when the removable communication card is connected to a network device.
