    Future of Smart Door Locks

    In the summer of 2017, the International Journal of Engineering Trends and Applications published a research article on the future of facial recognition door locks using Microsoft Face API. Future work in the field included the following:

    • If a blacklisted person attempted to open a smart door lock, the system will send an emergency alert to home or business owner.
    • Eventually the facial recognition technology would be able to differentiate between friends and strangers. Alerts can be sent directly to the account owner to let them know someone they don’t know is at the door.
    • A voice assistant can be added to smart door lock as a way to improve user experience.
    • A cloud-based database can be utilized to store the comings and goings of those who are at the door.
    • Transport layer security can add extra security to smart door locks that include facial recognition features.

    Some concerns around the proliferation of facial recognition data has slowed the spread of facial recognition technology in smart home devices. With companies facing backlash over mining social media for facial recognition data, there is mounting concern about how companies might use facial recognition data.

    Drawbacks of Smart Door Locks With Face Recognition

    A few problems can occur with smart door locks that include facial recognition. For one, accuracy has yet to be 100 percent. Due to this issue, there absolutely needs to be a backup method to enter the home. Fortunately, most of the locks available to do have alternative means of operation. So, if the facial recognition feature isn’t working properly, the lock should still function.

    Other drawbacks may arise from facial recognition technology in general. One concern involves the permanence of your facial recognition data. You can change a password if you have a problem, you cannot change your face. Privacy, as mentioned earlier, is also a concern with facial recognition technology. There’s evidence that some companies are being unethical in how they are collecting and selling facial recognition data. Additionally, facial recognition software has drawn some criticism for having accuracy issues with people of color, women, and some other minority groups.
