Infectious diseases commonly have incubation periods. The ability for an individual to demonstrate the absence of both the primary symptoms and disease exposure through a time duration longer than the incubation period prior to (or at) a checkpoint is a social benefit. Disclosed is a method for collecting and making available electronic documentation representing the measurement result(s) over a period of time of key vital signs along with location, time and personal identification at acquisition. The method allows for confidence that the documented information is authentic without the requirement of a trusted third party. The electronic documentation(s) can contain(s) the required information in the regular file contents or in the metadata of the file. The file may contain more information than is required at a given checkpoint and in this instance, a secure method for parsing the file or its metadata partially or to the required information of the checkpoint may be performed. |
