Wearable device authentication

Abstract

A wearable device is used to authenticate a user into a user account at a user device of the user. In particular, the wearable device may include a sensor configured to detect a body chemistry of the user. The wearable device may send a signal, such as a short range wireless signal, Bluetooth Low Energy or the like, to the user device to communicate the detected body chemistry to the user device. The user device may authenticate the user based on the body chemistry condition detected at the wearable device. In an embodiment, the wearable device may include an olfactory sensor configured to detect certain smell or scent of the user.

What is claimed is: 
     
         1 . A system comprising:
 a memory storing an account of a user including a body chemistry profile of the user;   one or more processors in communication with the memory and adapted to:   receive, from a wearable device of the user, body chemistry conditions detected at the wearable device;   compare the body chemistry conditions measured at the wearable device with the body chemistry profile of the user;   determine a similarity score based from comparing; and   authenticate the user based on the similarity score.   
     
     
         2 . The system of  claim 1 , wherein one or more types of body conditions are measured at the wearable device comprising one or more of a heart rate, a heartbeat pattern, a body temperature, a scent, a smell, an odor, a blood glucose, a blood oxygen level, a blood pressure, a galvanic skin response, and an ambient temperature. 
     
     
         3 . The system of  claim 1 , wherein the one or more processors are further adapted to automatically authenticate the user without requiring user credentials when the similarity score exceeds a threshold. 
     
     
         4 . The system of  claim 1 , wherein the user is authenticated and wherein the one or more processors are further adapted to:
 continue monitoring and comparing the body chemistry conditions measured at the wearable device with the body chemistry profile of the user; and   keep the user authenticated as long as the similarity score remains above a threshold.   
     
     
         5 . The system of  claim 1 , wherein the user is authenticated and wherein the one or more processors are further adapted to:
 continue monitoring and comparing the body chemistry conditions measured at the wearable device with the body chemistry profile of the user; and   stop authenticating the user when the similarity score decreases below a threshold.   
     
     
         6 . The system of  claim 1 , wherein the one or more processors are further adapted to require less user credentials to authenticate the user when the similarity score is above a threshold. 
     
     
         7 . The system of  claim 1 , wherein the account of the user comprises different body chemistry profiles for different situations or environmental settings and the one or more processors are further adapted to select a body chemistry profile for comparison with the body chemistry conditions detected at the wearable device. 
     
     
         8 . The system of  claim 1 , wherein the similarity score is determined based on a number of types of body chemistry conditions matching those of the body chemistry profile of the user. 
     
     
         9 . The system of  claim 1 , wherein types of body chemistry that are more unique to the user are weighted more in determining the similarity score than types of body chemistry that are less unique to the user. 
     
     
         10 . The system of  claim 1 , wherein the one or more processors are further adapted to:
 analyze the body chemistry conditions detected at the wearable device when the user is authenticated;   determine patterns of the body chemistry conditions; and   update the body chemistry profile of the user based on the patterns.   
     
     
         11 . The system of  claim 1 , wherein the one or more processors are further adapted to:
 determine that the wearable device is separated from the user based on the body;   chemistry conditions detected at the wearable device; and   stop authenticating the user when the wearable device is separated from the user.   
     
     
         12 . The system of  claim 1 , wherein the one or more processors are further adapted to:
 determine a correlation between a first type of body chemistry and a second type of body chemistry; and   authenticate the user based on the correlation.   
     
     
         13 . A wearable device comprising:
 a sensor configured to detect a body chemistry condition of a user;   a communication device configured to communicate body chemistry conditions measured by the sensor to a user device of the user; and   a controller configured to:
 encode the body chemistry condition in a signal; and 
 control the communication device to emit the signal for user authentication at the user device. 
   
     
     
         14 . The wearable device of  claim 13 ,
 wherein the wearable device comprises a watch comprising:
 a watch case; and 
 a fastening portion configured to fasten the watch case to the user; 
   wherein the sensor is disposed on an inner surface of the watch case contacting the user when the wearable device is worn by the user.   
     
     
         15 . The wearable device of  claim 13 ,
 wherein the wearable device comprises a band; and   wherein the sensor is disposed on an inner surface of the band contacting the user when the wearable device is worn by the user.
