Perspective 1

The method for authenticating a user in the question appears to be similar to certain aspects of the following patents:

1. [Patent 10057053, Claim 9, based on USPTO LEGAL GROUND 35 USC 102(a)] teaches a process of authenticating a mobile device on a wireless network. It does so by obtaining a secret key associated with the mobile device, evaluating a message authentication code based on the secret key to produce an output value, and determining that a response from the mobile device matches an expected response. This seems similar to the method in the question where an application running on a mobile phone receives a unique user input, processes it, and generates a secret. This secret is then stored on the mobile phone and can be retrieved when the unique user input is received again.

2. [Patent 10958631, Claim 4, based on USPTO LEGAL GROUND 35 USC 102(a)] mentions a subscriber hardware module for use in a user device that stores a shared secret key, uses the shared secret key in an authentication procedure, and derives a further secret key. This is similar to the process in the question where a secret is generated from a unique user input and stored on the mobile phone.

3. [Patent 9628481, Claim 1, based on USPTO LEGAL GROUND 35 USC 102(a)] discloses a base station that receives an access request message from a mobile unit. The message includes a message authentication code formed using a first key, which is derived from a second key. Access is granted to the mobile unit based on the message authentication code and the value of a first counter. This seems to have a semantic similarity to the process in the question where the mobile phone receives a first communication from a remote computer-based station asking for user credentials.

4. [Patent 9288310, Claim 11, based on USPTO LEGAL GROUND 35 USC 102(a)] discusses a smart card that sends a first request to a roaming entity in a telecommunication network and receives a response from an application server. The response includes a personalization command and an admin code. If the admin code is valid, a secure session is established with a personalization server. This patent claim seems to have a semantic overlap with the question where the mobile phone receives a first communication from a remote computer-based station.

In conclusion, the four patent claims listed above exhibit overlapping or similar technical features with the method for authenticating a user described in the question. These features include the generation and storage of secret keys for authentication, the reception and processing of requests and responses for user credentials, and the establishment of secure sessions for communication.

Perspective 2

Based on the provided context, several patents have claims that could be similar or overlapping with the method for authenticating a user described in the question. The relevant patents are:

1. Patent 10057053, Claim 9: The claim describes a process for authenticating a mobile device where a secret key associated with the mobile device is used to produce an output value. This output value is used to obtain a session key and an expected response. This is similar to the process described in the question where a unique user input is processed to generate a secret, that is stored and used for subsequent authentications. [Patent 10057053, Claim 9 based on LEGAL GROUND 35 USC 103(a)]

2. Patent 10958631, Claim 4 and Claim 1: These claims describe a process where a shared secret key is used for authentication and a further secret key is derived for subsequent local authentication. This is comparable to the method in the question where a secret is generated and stored for future authentications. [Patent 10958631, Claim 4 and Claim 1 based on LEGAL GROUND 35 USC 102(a)]

3. Patent 9628481, Claim 1 and Claim 19: These claims involve a process where a first key is derived from a second key and a counter, and this first key is used for the formation of a message authentication code. Even though the method of generating the key is different, the principle of generating a key for authentication is similar to the method described in the question. [Patent 9628481, Claim 1 and Claim 19 based on LEGAL GROUND 35 USC 102(c)]

4. Patent 7430414, Claim 2: This claim discusses a method of providing an identifier to a server for request establishment. Though this does not specifically involve generating and storing a secret, the concept of using an identifier for subsequent access is parallel to the described method in the question. [Patent 7430414, Claim 2 based on LEGAL GROUND 35 USC 102(b)]

In summary, while there are similarities in the concept of using a generated secret or key for subsequent authentications, the specifics of how the secret or key is generated and used vary among the claims. As a patent lawyer, you would need to carefully scrutinize the exact method and process described in the question against each claim to determine potential overlaps or conflicts. This analysis would form the basis of any legal interpretations or explanations.
