Amazon offered Congress and other policymakers a set of guidelines regarding facial recognition technologies—of which it is one of the world’s foremost suppliers with its Rekognition software.

In a blog post authored by Michael Plunke, vice president of global public policy for Amazon Web Services, the company acknowledged potential pitfalls and misuses of facial recognition tech but argued for “open, honest and earnest dialogue” among users, tech companies and policymakers as opposed to outright banning or condemning it.

In January, some Amazon shareholders argued for the company to stop selling facial recognition software to the government—over potential violations of civil and human rights—until the company’s board of directors could review societal impacts of the technology. In recent weeks, some cities, including San Francisco, have called for banning facial recognition outright.
