Against the backdrop of an ongoing public debate regarding the use of the ISA’s (Shin Bet) cellular tracking technology for pinpointing contacts with COVID-19 carriers, the Israeli startup Viziblezone has launched a dedicated solution that allows organizations to track all of the employees who came into contact with an employee diagnosed with COVID-19, without invading their privacy.
The company announced first collaboration with the Israeli cyber and intelligence Verint, which employs thousands of employees worldwide. Verint will implement the solution on its premises, and distribute it to its customers. Viziblezone is also in talks with other organizations in Israel and abroad concerning the adoption of its new app.
The Data is kept in the Smartphone
Viziblezone’s solution is based on the smartphone’s Bluetooth: Whenever it receives a radio signal from a nearby smartphone, it it assigns the “encounter” with a random identification number and encrypts the data in a contact log file stored on the device. Thus, the smartphone of each employee records all of the contacts between them, each on their own device, without the information being transferred to an external server.
In the event that a person in the organization is diagnosed with COVID-19, he informs the person in charge of COVID-19 on behalf of the organization and receives a single-use code that allows him to send his contact log file to all of the devices in the organization, via the local server. The rest of the devices cross-check with the personal contact log stored within them, to see if there is a documentation of encounter. When a match is detected, the employee is alerted that he has been exposed to a COVID-19 patient.
Maintaining Business Continuity
The algorithm calculates how long the encounter lasted and what was the estimated distance between the workers, and thus determine if the encounter exceeded the social distancing rules. This clever concept does not involve penetrating a device or gaining access to irrelevant private information.
Founder and CEO Gabi Ofir, told Techtime that the app is designed for the workplace. “The solution is not intended for the public space, but for companies and organizations that employ a considerable amount of employees. It can prevent a situations in which a diagnosis of a COVID-19 patient would lead to sending all of the employees off to quarantine.”
From Automotive to Healthcare
Viziblezone was founded in early 2019 by Gabi Ofir, former system architect at Motorola, to develop life-saving smartphone-based software solutions for the roads. When the system detects a potentially life-threatening situation, such as a pedestrian, cyclist or scooter rider crossing a road, the user’s smartphone transmit warning signals to nearby cars concerning a potential for collision.
Ofir: “In the face of The COVID-19 we had to make a decision on whether to furlough our employees or to somehow adapt our technology to the situation. Thus we decided to utilize our technology to provide monitoring contacts solution that can help with business continuity. We had to overcome critical technological challenges: maximum power saving, processing the Bluetooth signals, neutralizing interference from other signals and more. The result: we achieved 99% accuracy rate in tracing the contacts for a period of two weeks back.”
