Systems, Methods and Devices for Trusted Transactions

A device for transmitting information to another device and receiving information from the other device, comprising:

• a central processing unit (CPU) for processing data;
• a power supply for powering said device;
• a transmitter for transmitting data;
• a receiver for receiving data;
• a converter consisting of one at least one of (1) a transducer for transducing physical information to an analog information and an A/D converter for converting said analog information to digital format and (2) a transducer for transducing physical information to digital format;
• a memory for storing data in non-transitory form;
• wherein said memory stores, in non-transitory form, data related to identity of a device holder;
• a number generator for generating numbers;
• a cipher;
• and
• wherein said device is designed to respond to an action of said device holder of said device, by using said converter to convert physical information of said device holder to digital information of said device holder;
• wherein said cipher receives said digital information of said device holder during a transaction, and uses the received digital information of the device holder to generate ciphered output data during said transaction;
• wherein said transmitter is designed to transmit said ciphered output data to said other device during said transaction.

A method for transmitting information from a handheld device to another device and receiving information from the other device, wherein said one device comprises a central processing unit (CPU) for processing data;

• a power supply for powering said device;
• a transmitter for transmitting data;
• a receiver for receiving data;
• a converter consisting of at least one of (1) a transducer for transducing physical information to an analog information and an A/D converter for converting said analog information to digital format and (2) a transducer for transducing physical information to digital format;
• a memory for storing data in non-transitory form;
• a cipher;
• and a number generator;
• the method comprising:
• said device storing in said memory, in non-transitory form, data related to identity of a device holder;
• said device responding to an action of said device holder of said device, by using said converter to convert physical information of said device holder to digital information of said device holder;
• said cipher receiving said digital information of said device holder during a transaction, and said cipher using the received digital information of the device holder to generate ciphered output data during said transaction;
• said transmitter transmitting said ciphered output data to said other device during said transaction.

A method for authenticating a party to a transaction, comprising:

• storing in a handheld device, a unique device identification (unique device ID);
• initially transducing, in a transducer of the handheld device, biometric data of a person;
• securing, in the handheld device, the transduced biometric data, using a cipher in said handheld device;
• initially, transmitting from the handheld device the secured biometric data, over a network;
• subsequently, ciphering transaction information during a transaction, in the handheld device, using said cipher, to generate ciphered transaction information;
• then, transmitting said ciphered transaction information, over the network.

A handheld device for authenticating a party to a transaction, comprising:

• a unique device identification (unique device ID) stored in the device;
• a transducer designed at least to transduce biometric data of a person;
• a cipher, designed to secure the transduced biometric data;
• a transmitter designed to transmit the secured biometric data, from the handheld device, over a network;
• the cipher also designed to cipher transaction information during a transaction, to generate ciphered transaction information;
• and
• the transmitter designed to transmit the ciphered transaction information, over the network.
