and a chain of custody engine associated with the wearable device, the chain of custody engine to provide a chain of custody validation for the biometric information, validation information and the sleep information from the wearer to the one or more web servers to ensure compliance by the user of rules related to the gathering of the biological data. ### Claim 2 (depends on 1) The apparatus in accordance with claim 1, further comprising a transceiver coupled with the wearable device, the transceiver for transmitting the biometric information, validation information and sleep information as a digital signal to one or more web servers via a communications network. ### Claim 3 (depends on 2) The apparatus in accordance with claim 2, wherein the wearable device includes a housing to be worn around the wearer's wrist. ### Claim 4 (depends on 3) The apparatus in accordance with claim 3, wherein the authentication sensor is connected with the housing. ### Claim 5 (depends on 1) The apparatus in accordance with claim 1, wherein the wearable device further includes a positioning sensor to establish a geographical position of the wearer. ### Claim 6 (depends on 1) The apparatus in accordance with claim 1, wherein the wearable device further includes an accelerometer to determine a direction and rate of speed of the wearer. ### Claim 7 (depends on 1) The apparatus in accordance with claim 1, wherein the computer processor generates the biometric information according one or more biometrical algorithms. ### Claim 8 A computer-implemented method for maintaining a chain of custody of data gathered from a wearer by one or more biological sensors of a wearable device, the method comprising: authenticating, by an authentication sensor connected with the wearable device, an identity of the wearer of the wearable device; generating biometric information by a computer processor of the wearable device based on the biological data and according one or more biometrical algorithms, the biometric information including validation information to validate the wearer as a source of the biological data gathered by each of the one or more sensors, the biometric information further including sleep information to provide a sleep profile of the wearer; and maintaining, by the computer processor, a chain of custody of the biometric information, validation information and the sleep information from the wearer to the one or more web servers to ensure compliance by the user of rules related to the gathering of the biological data and associated with the identity of the wearer. ### Claim 9 (depends on 8) The computer-implemented method in accordance with claim 8, further comprising: transmitting, by a transceiver coupled with the wearable device, at least one of the biometric information, the validation information and the sleep information to one or more web servers via a communications network. ### Claim 10 (depends on 8) The computer-implemented method in accordance with claim 8, further comprising: establishing, by a positioning sensor of the wearable device, a geographical position of the wearer. ### Claim 11 (depends on 8) The computer-implemented method in accordance with claim 8, further comprising: determining, by an accelerometer of the wearable device, a direction and rate of speed of the wearer. ### Claim 12 (depends on 8) The computer-implemented method in accordance with claim 8, wherein the authentication sensor is a heartbeat sensor to monitor cardiac rhythms of the wearer.
