Abstract

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).

Claims

1. A personal communication apparatus (10) for generating a verifiable recording of a transaction (240), the transaction comprising an exchange of information, the apparatus (10) including:

a) a receiving component for receiving a transaction between a user (100) of the apparatus and a remote person, and for receiving biometric data of the remote person;

b) a protection component for protecting the transaction with the biometric data;

c) a memory (30) for storing the protected transaction (240); and

d) a recording component for recording the transaction (240) protected with the biometric data on the memory (30).

2. A personal communication apparatus as claimed in claim 1, wherein the protection component is capable of protecting the transaction with the biometric data by generating one or more access keys (RANKY), encrypting the transaction with the one or more access keys (RANKY), protecting the one or more access keys with the biometric data, and storing the protected one or more access keys in the memory (30).

3. A personal communication apparatus as claimed in claim 2, wherein the memory comprises a keylocker (330) and the protection component is capable of storing the protected one or more access keys in the memory (30) by storing the one or more access keys (RANKY) together with the biometric data in the keylocker (330).

4. A personal communication apparatus as claimed in claim 2, wherein the protection component is capable of protecting the one or more access keys with the biometric data by encrypting the one or more access keys (RANKY), using a biometric key (BIOKY) to generate one or more security keys (ENCKY) for use in accessing the protected transaction (240), the biometric key (BIOKY) corresponding to or being generated from the biometric data.

5. A personal communication apparatus as claimed in claim 1, wherein the receiving component is capable of receiving biometric data from a biometric measuring means (80) which includes one or more from:

fingerprint imaging of one or more digits of a human hand, analysis of phonetic content of a vocal utterance, facial imaging followed by image analysis, human iris image analysis, dental imaging, or ear contour analysis.

6. Software executable on a computing means for making the computing means capable of functioning as the personal communication apparatus (10) of claim 1.

7. A personal communication apparatus (10) operable to support authentication of a transaction therein, the transaction comprising an exchange of information, characterized in that the apparatus (10) includes:

a) a memory (30) for storing a transaction protected with earlier biometric data (240); and

b) an authentication component for providing access to the protected transaction if biometric data measured by a biometric measuring means (80) corresponds to the earlier biometric data.

8. A personal communication apparatus (10) as claimed in claim 7, wherein the authentication component is capable of providing one or more access keys (RANKY) for decrypting the protected transaction, provided that the biometric data correspond to the earlier biometric data, and further including a decrypting component (20) for using the one or more access keys (RANKY) to decrypt at least part of the protected transaction (240).

9. A personal communication apparatus (10) as claimed in claim 8, wherein the authentication component is capable of obtaining the one or more verified access keys (RANKY) by decrypting one or more security keys (ENCKY) with one or more measured biometric keys (BIOKY).

10. A personal communication apparatus (10) as claimed in claim 8, wherein the one or more access keys are maintained in a keylocker (330) associated therein with earlier biometric data, such that presentation of the measured biometric data to the keylocker (330) enables access, subject to the earlier biometric data in the keylocker (330) corresponding to the measured biometric data, to the one or more access keys (RANKY).

11. A personal communication apparatus as claimed in claim 7, wherein the authentication component is capable of receiving biometric data from a biometric measuring means (80) which includes one or more from:

fingerprint imaging of one or more digits of a human hand, analysis of phonetic content of a vocal utterance, facial imaging followed by image analysis, human iris image analysis, dental imaging, or ear contour analysis.

12. Software executable on a computing means for making the computing means capable of functioning as the personal communication apparatus (10) of claim 7.
