Approaches presented herein enable identifying an individual exposed to an illness carried by another individual by securely tracking interactions between individuals and using this information during a public health emergency to alert a public health authority and/or individuals who might be at risk of exposure to an illness. Specifically, a first mobile device of a user detects a second mobile device of another individual via low-energy radio frequency communication. The first device records contact data, including an identification of the second device, a distance between the devices, and a duration that the devices are within a specified distance from one another, and then encrypts and stores this contact data. In response to a public health emergency, the first device conducts an exposure analysis of the stored set of data using distance and duration thresholds to determine if the user came into contact with an individual carrying an illness.
Claim CLM-00001. 1. A method for identifying an individual exposed to an illness carried by another individual, the method comprising:
detecting, by a first mobile device, a second mobile device using a low-energy radio frequency communication; recording a set of data comprising: an identification number of the second mobile device, a distance between the first mobile device and the second mobile device, and a duration that the second mobile device is within a specified distance to the first mobile device; encrypting and storing the set of data in a data storage; and in response to an identification of an individual carrying an illness, conducting an exposure analysis of the stored set of data, the exposure analysis based on criteria thresholds comprising: a pre-specified distance and a pre-specified duration.
Claim CLM-00009. 9. A computer system for identifying an individual exposed to an illness carried by another individual, the computer system comprising:
a memory medium comprising program instructions; a bus coupled to the memory medium; and a processor, for executing the program instructions, coupled to a contact tracking tool via the bus that when executing the program instructions causes the system to:
detect, by a first mobile device, a second mobile device using a low-energy radio frequency communication;record a set of data comprising: an identification number of the second mobile device, a distance between the first mobile device and the second mobile device, and a duration that the second mobile device is within a specified distance to the first mobile device;encrypt and store the set of data in a data storage; andin response to an identification of an individual carrying an illness, conduct an exposure analysis of the stored set of data, the exposure analysis based on criteria thresholds comprising: a pre-specified distance and a pre-specified duration.
Claim CLM-00016. 16. A computer program product for identifying an individual exposed to an illness carried by another individual, the computer program product comprising a computer readable storage device, and program instructions stored on the computer readable storage device, to:
detect, by a first mobile device, a second mobile device using a low-energy radio frequency communication; record a set of data comprising: an identification number of the second mobile device, a distance between the first mobile device and the second mobile device, and a duration that the second mobile device is within a specified distance to the first mobile device; encrypt and store the set of data in a data storage; and in response to an identification of an individual carrying an illness, conduct an exposure analysis of the stored set of data, the exposure analysis based on criteria thresholds comprising: a pre-specified distance and a pre-specified duration.
