Method and computer programs for determining human condition of a target

A method for determining human condition of a target, the method comprising performing by one or more processors the following steps:

• obtaining, from a database, validated geolocation data points of said target, each validated geolocation data point comprising three parameters including longitude, latitude and timestamp of a given geolocation, and being associated with an International Mobile Subscriber Identity, IMSI;
• determining whether a given trajectory depicted by a set of the validated geolocation data points belongs to a human by computing a plurality of models using a behavioural algorithm, the plurality of models including two or more of the following models:
• a first model evaluating a likelihood of geographical location in terms of human habitability,
• a second model evaluating a likelihood of social interaction, identifying places that are typically frequented by humans, and
• a third model evaluating a likelihood of the given trajectory being physically possible for a human within a specified time frame;
• providing a weight to each one of the computed plurality of models;
• and
• computing a human condition score based on a combination of the provided weights.
