Reporters obtained the following quote from the background information supplied by the inventors: “The present disclosure relates generally to systems and methods that enable access control for digital objects based on measured physiological signals of a user.
“The human nervous system includes a large number of neurons that cooperate with one another to enable mental activities. By analyzing the communications between these neurons while a person performs various tasks, patterns may be observed and associated with particular mental activities and moods of the person. Electroencephalograph (EEG) devices include a number of electrodes that are typically positioned at locations along the scalp and face of a person and can measure patterns of voltage fluctuations that result from electrical communications between the person’s neurons. For example, a person connected to an EEG device may have a particular pattern of electrical activity that can be identified when the patient thinks of a particular object, place, movement, or emotion. As such, an EEG device can be utilized as a computer input device, whereby patterns of voltage fluctuations of a user’s brain may be translated into computer commands or actions (e.g., mouse movements, keyboard strokes), which is particularly useful for computer users that may not be capable of using traditional computer input devices.”
In addition to obtaining background information on this patent, NewsRx editors also obtained the inventors’ summary information for this patent: “One or more specific embodiments of the present disclosure will be described below. In an effort to provide a concise description of these embodiments, all features of an actual implementation may not be described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions must be made to achieve the developers’ specific goals, such as compliance with system-related and business-related constraints, which may vary from one implementation to another. Moreover, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.
“As used herein, a “digital object” refers to digital property of a user that exists as one or more pieces of information, such as user credentials (e.g., user names, passwords, passphrases, personal identification numbers (PINs), encryption keys, activation keys) and user accounts (e.g., name of account holder, account number, expiration date, security code, billing address). While a digital object is a collection of information, it should be noted that digital objects may store information that can be used to access real world locations, such as grant access to enter buildings or vehicles having digital locking mechanism. As used herein, “physiological signals” include any measurable physiological activity that is associated with the operation of a user’s brain, including electrical signals (e.g., brain waves), magnetic signals, optical signals, sound signals, chemical signals, and so forth. As used herein, a “brain pattern” refers an identifiable set of measured physiological signals that can be reproduced by user. As used herein, “projecting” refers the action of a user’s mind, such as intentionally thinking about (e.g., focusing on, imagining, picturing, recalling) a particular target in order to generate a particular brain pattern. As used herein, a “target” refers to an object, person, place, feeling, or another suitable subject that a user can project to generate a unique brain pattern. As used herein, a “trigger” refers to a particular stimuli (e.g., auditory, visual, tactile) provided by the device to a user to cause the user to project a particular target, such that the corresponding brain pattern of the user may be measured and identified. As used herein, an “agent” refers to a representative person or device that acts on behalf of a company or person (e.g., a salesperson, a customer service representative, a register, a payment system, a website) in the normal course of business.
“Present embodiments are directed toward systems and methods that enable access control for digital objects based on measured physiological signals of a user. More specifically, present embodiments provide a system that is trained to associate a user’s brain patterns with particular digital objects, and subsequently enables the user to access the digital object by reproducing the particular brain patterns. For example, a digital object that is a password for a website may be associated with a particular brain pattern of the user that is generated and measured when the user projects a target, such as the logo of the company that operates the website. As such, present embodiments enable the user to make use of a digital object by projecting the logo of the company, such that the user need not remember the information of the digital object itself (e.g., the password). Additionally, in certain embodiments, a first user is enabled to grant a second user the ability to associate their own brain pattern with a digital object of the first user, providing the second user revocable access to use the digital object without compromising the information of the digital object itself. Further, as discussed below, present embodiments may enable a user to deliver information of a digital object to another party without the user having to speak or type sensitive information associated with the digital object, thereby improving the privacy and security of the user in public spaces.
