The mindset behind a new law to prohibit the use of facial recognition and other security-related technologies by San Francisco police and other city agencies is obvious in the name of the new ordinance: “Stop Secret Surveillance.”

Ordinance to stop secret surveillance

The San Francisco Board of Supervisors passed the ordinance 8-1 with two abstentions on May 14, and there will be another vote next week before it becomes law.

We have an outsize responsibility to regulate the excesses of technology precisely because they are headquartered here"

The irony of such a law emanating from northern California, where tech giants promote the use of numerous technologies that arguably infringe on privacy, is not lost on Aaron Peskin, the city supervisor who sponsored the bill. “We have an outsize responsibility to regulate the excesses of technology precisely because they are headquartered here,” he told the New York Times.

Regulating facial recognition technology 

Although the facial recognition aspects of the ordinance have been the most publicised, it also targets a long list of other products and systems.

According to the ordinance, "Surveillance Technology" means “any software, electronic device, system utilising an electronic device, or similar device used, designed, or primarily intended to collect, retain, process, or share audio, electronic, visual, location, thermal, biometric, olfactory or similar information specifically associated with, or capable of being associated with, any individual or group.” Broadly interpreted, that’s a lot of devices.

Includes biometrics, RFID scanners

The ordinance lists some examples such as automatic license plate readers, gunshot detection hardware and services, video and audio monitoring and/or recording equipment, mobile DNA capture technology, radio-frequency ID (RFID) scanners, and biometric software or technology including facial, voice, iris, and gait-recognition software and databases.  

Among the exceptions listed in the ordinance are physical access control systems, employee identification management systems, and other physical control systems; and police interview rooms, holding cells, and internal security audio/video recording systems.

The ordinance list includes automatic license plate readers, video and audio monitoring, mobile DNA capture technology, RFID scanners, and biometric software.
The ordinance ban applies to city departments and agencies, not to the general public and exceptions include physical access control systems, employee identification management systems, and internal security audio/video recording systems

Airport security not part of ordinance

The ban only applies to city departments and agencies, not to private businesses or the general public. Therefore, San Franciscans can continue to use facial recognition technology every day when they unlock their smart phones.

And technologies such as facial recognition currently used at the San Francisco airport and ports are not impacted because they are under federal jurisdiction. Furthermore, the San Francisco police department does not currently use facial recognition anyway, although it has been deployed in places such as Las Vegas, Orlando, Boston and New York City.

Safeguarding privacy of citizens

The ordinance appears to have a goal of avoiding government uses of technologies that can invade individual privacy, seeking to avoid worst-case scenarios such as an existing system in China that uses millions of surveillance cameras to keep close tabs on the Uyghurs, a Muslim minority population.

Any new plans to use surveillance technology must be approved by the city government, and any existing uses must be reported and justified by submitting a Surveillance Technology Policy ordinance for approval by the Board of Supervisors within 180 days.

Surveillance technology policy

Banning use of facial recognition just when its capability is being realised is counterproductive

But might such a ban on technology uses undermine their potential value as crime-fighting tools just when they are poised to become more valuable than ever?

Ed Davis, a former Boston police commissioner, told the New York Times it is “premature to be banning things.” He notes: “This technology is still developing, and as it improves, this could be the answer to a lot of problems we have about securing our communities.

Technology development doesn’t happen in a vacuum and banning uses of facial recognition and other technologies just when their capabilities are being realised is counterproductive. We should be thoughtful, deliberate and transparent in how we embrace new technologies. However, discarding them out-of-hand using emotionally charged words such as “secret surveillance” does not promote the best use of technology to the benefit of everyone.

What are the security challenges of protecting SMBs?
What are the security challenges of protecting SMBs?

Small and medium-sized businesses (SMBs) make huge contributions to the economy overall. Considered individually, they may not be as large as companies in the enterprise market, but they have big requirements when it comes to security. SMBs also present unique challenges to security manufacturers and integrators seeking to serve their needs. We asked this week’s Expert Panel Roundtable: What are the security challenges of protecting small and medium-sized businesses (SMBs)?

Our Expert Panel Roundtable is an opinionated group. However, for a variety of reasons, we are sometimes guilty of not publishing their musings in a timely manner. At the end of 2020, we came across several interesting comments among those that were previously unpublished. Following is a catch-all collection of those responses, addressing some of the most current and important issues in the security marketplace in 2021.

Smart Offices: How is mobile ID changing the way we access the office?
Smart Offices: How is mobile ID changing the way we access the office?

If you’re a security or facilities manager, you may already be aware of the quiet revolution that’s taking place across businesses and organisations up and down the country. By the end of 2020, 20% of all ID and access control systems featured mobile capability, and this is set to increase by a further 34% over the next three years. There’s no doubt that using a smartphone or mobile device in place of traditional credential and access control is a growing trend that’s only been sped up by the pandemic. It’s true that many businesses are still very much focused on remote working, although many are now starting to implement new-and-improved strategies that are better suited to protect the workforce moving forward. Mobile ID systems As the next normal becomes clearer, businesses will be reviewing procedures such as access control, occupancy monitoring, reducing touch points and tracking visitors. Mobile ID systems are ideally suited to this task. But what are the key reasons for considering such a setup in 2021? But why is this new technology so well-suited to future-proof your physical access system, and why is it becoming so popular? Eradicating outdated legacy credentials Have you seen just how vulnerable outdated Proximity card technology can be? Low-frequency 125kHz cards can be cloned in a matter of seconds with the use of cheap, readily available tools. Despite their weaknesses, they are still used by a huge majority of businesses – big and small. All smartphones include two industry-standard features that make them perfect for operating a secure, contactless credential Replacing such a system with a mobile-enabled system is one of the best ways to increase security ten-fold. Thanks to a cloud-based infrastructure, mobile ID offers best-in-class security and cryptography. All smartphones include two industry-standard features that make them perfect for operating a secure, contactless credential. Bluetooth Smart and NFC (Near Field Communication) make them the best product to operate such a credential via a secure app. If you’re looking for best-in-class security in 2021, mobile access is most definitely the way forward. Removing touch points across the business Reducing touch points and the adoption of touchless facilities has become a key priority for businesses in the wake of COVID-19. Even as businesses start to return to the office and operate a home/office split, it will be imperative that unnecessary contact is kept to an absolute minimum between staff. The traditional issuance of identification and access control credentials can pose problems in this regard. Facility and security managers who are responsible for onboarding and processing ID have done the process face to face. Mobile access makes it possible to carry this process out without people coming into direct content. First, the security manager has access to a secure portal, allowing them to create, manage and edit credentials anywhere. They can upload and remotely transfer mobile ID and access control credentials directly to users’ smartphones over the air. Via the secure app, users can view and see their credentials and immediately begin using it for ID and access control by simply placing their smartphone over card readers. Enabling a more flexible way of working The way in which we work has changed for good. Even as people more people return to the office in 2021, a majority of businesses will be operating a home/office split indefinitely. This once again reinforces the need for a smarter, more adaptable onboarding system. Implementing mobile ID is the perfect way of doing this: over-the-air delivery of credentials and security data is now a given, helping businesses create the perfect balance between the home and the office. No longer do people have to come into the office for the onboarding process. Increasing convenience and user experience More often businesses are realising the value mobile ID can have for enhancing the work experience as well as security Ok, so mobile ID is the perfect way of increasing security and adapting workplaces to a post-COVID way of working. And we’ve not even touched on the most obvious advantage yet: Convenience. How many times have you forgotten your ID card? We’re sure it’s more times than you forget your smartphone. These powerful processors have become intertwined with the way we carry out tasks on a daily basis. They’re so vital that people will soon notice if they’ve forgotten it. From an employee’s perspective, mobile ID and access control is simple, convenient and extremely user-friendly. More and more businesses are realising the value mobile ID can have for enhancing the work experience as well as security. From the employer’s perspective, mobile ID means it’s easier for administrators to manage access and credentials. Future-proofing access control now will ensure that in the longer term, mobile ID is well worth the investment. The annual expenditure of printing ID cards and purchasing credentials can be vast, while reissuance costs can also quickly add up for larger organisations. These issues are a thing of the past for businesses using mobile ID. Mobile ID perfect tool for 2021 and beyond Until mobile ID, new and improved credentials’ main focus was on increasing security. Mobile ID not only delivers that, but it also provides a more convenient way of accessing the office in a way that’s perfectly suited to returning to the office in 2021. If there was ever a time to upgrade, now is the time. Summing up, mobile access is changing the way we access the office by: Eliminating weak links in security systems such as outdated legacy card technologies Eradicating the need for touch points across multiple areas of the workplace Enabling a smarter, more flexible approach to onboarding Increasing convenience – for both employers and employees.
