Purpose: The disclosure addresses faults in conventional multi-factor authentication (MFA), particularly over-reliance on a single verification method. The patent notes that if a user's email is compromised, password resets and one-time codes sent to that email can be exploited to access other accounts. It calls for a system combining verification methods so dependence on a single, possibly compromised, method is eliminated, and that dynamically determines how much verification is needed.
Plain-language scope: Per the excerpt, a server dynamically determines a necessary verification score a user must obtain before accessing requested resources. The score is based on context and risks associated with the connection request, such as connection origin and how unusual the request is determined to be. The user then collects verification points through multiple verification methods to gain access.
Classifications include: H04L63/08 (authentication of entities), H04L63/0861 (biometric features), H04L63/083 (passwords), H04L63/0876 (terminal identity/device fingerprint), H04L63/105 (multiple levels of security), H04L63/1433 (vulnerability analysis), H04L2463/082 (multi-factor authentication), and H04L43/04 (processing captured monitoring data).

Proceedings on file (0)
All PTAB activity →AIA trial proceedings (IPR / PGR / CBM) filed at the USPTO Patent Trial and Appeal Board against this patent. Sourced from the USPTO Open Data Portal and refreshed every six hours; each proceeding number deep-links to the PTAB E2E docket.
No PTAB proceedings on file. This patent has not been challenged via IPR, PGR, or CBM. The absence is itself a signal — well-asserted patents eventually attract IPRs. The LLM analysis below may surface filings the ODP feed hasn’t indexed yet.
PTAB challenges
AIA trial proceedings at the USPTO Patent Trial and Appeal Board — IPR, PGR, and CBM. Petitioners, judge panels, claim-level invalidation outcomes from Final Written Decisions, and Federal Circuit appeals. The single most important defensive datapoint after litigation history.
Assignment history
Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.
Prior art
Earlier patents, publications, and products that may anticipate or render the claims unpatentable.
Obviousness
Combinations of prior art that suggest the claimed invention would have been obvious under 35 U.S.C. § 103.
Extensions
Patent term adjustments, term extensions, continuations, divisionals, family members, and expiration dates.
Derivative works
Defensive disclosure: derivative variations of each claim designed to render future incremental improvements obvious or non-novel.
