Prior art

To identify the most relevant prior art for US patent 11157606, I will use the information available directly from the patent text itself, as it explicitly lists its cited prior art. The USPTO provides tools for patent searching, including the Patent Public Search tool, which allows users to search for patents and patent application publications. These tools can be used to find prior art and analyze claims.

US Patent 11157606, titled "Facial recognition authentication system including path parameters," lists several prior art documents. I will now extract and present the most relevant prior art based on the citations within the patent document.

Prior Art Cited in US Patent 11157606:

The patent text explicitly references its priority claim from US14/839,505. This suggests that US9953149B2 (associated with the patent/US9953149B2/en link) is a key prior art document, likely an earlier patent in the same family.

1. US 9953149 B2

• Full Citation: US9953149B2 - "Facial recognition authentication system including path parameters" (Based on the provided link patent/US9953149B2/en within the patent text for the priority claim from US14/839,505).
• Publication/Filing Date: The priority date for US11157606B2 is listed as 2014-08-28. Given that US9953149B2 is linked to the priority claim, its filing date would be on or before this date, and its publication date would be later. The current patent 11157606B2 itself lists a "Priority claimed from US14/839,505" on "2015-08-28" which links to patent/US9953149B2/en.
• Brief Description: This patent (or application it stemmed from) would describe a facial recognition authentication system that includes the use of "path parameters" during enrollment and authentication. This would involve a user moving a mobile device (or their face relative to a camera) in a specific path while images are captured. Biometric data from these images and the path parameters are then used for authentication, enhancing security against spoofing. This is foundational to the current patent.
• Potential Anticipation (35 U.S.C. § 102): US9953149B2 likely anticipates many of the core claims of US11157606B2, particularly those related to:
  • A method for authenticating a user by obtaining a plurality of authentication images and path parameters during movement. (e.g., elements of claims 1, 11, 19).
  • Comparing authentication biometric information and authentication movement with stored enrollment biometric information and enrollment movement. (e.g., elements of claims 1, 11, 19).
  • The use of sensors (accelerometer, gyroscope, magnetometer) to determine movement paths. (e.g., elements of claims 3, 13, 21).
  • The general concept of using facial recognition combined with device movement for liveness detection and enhanced security.

Further analysis would require obtaining the full text of US9953149B2 and comparing its claims and disclosures directly to those of US11157606B2. Based solely on the information provided in US11157606B2, US9953149B2 appears to be a direct predecessor or related application covering similar inventive concepts.
