Abstract
According to various, but not necessarily all, embodiments there is provided an apparatus comprising means for: determining at least two locations at which a user touches a device; selecting a first location and a second location from the at least two locations to define a transmission path for an acoustic signal through the user; applying an acoustic signal to the user through the first location; detecting an acoustic signal transmitted through the user at the second location; and analysing the detected acoustic signal to determine if it is indicative of transmission of the applied acoustic signal through an authorised user based on a known bioacoustic signature of the authorised user.
Claims16
An apparatus comprising:
- at least one processor;
- and
- at least one non-transitory memory including computer program code;
- the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to:
- determine at least two locations at which a user touches a device;
- select a first location and a second location from the at least two locations to define a transmission path for an acoustic signal through the user;
- apply an acoustic signal to the user through the first location;
- detect an acoustic signal transmitted through the user at the second location;
- analyse the detected acoustic signal to determine if it is indicative of transmission of the applied acoustic signal through an authorised user based on a known bioacoustic signature of the authorised user;
- wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to:
- for the at least two touch locations, determine which parts of the user's hand provide the touch contact;
- and
- wherein selecting the first location and a second location comprises:
- identifying available transmission paths, for an acoustic signal, through the user between the parts of the user's hand which provide the touch contact;
- and selecting one of the available transmission paths.
A method comprising:
- determining at least two locations at which a user touches a device;
- selecting a first location and a second location from the at least two locations to define a transmission path for an acoustic signal through the user;
- applying an acoustic signal to the user through the first location;
- detecting an acoustic signal transmitted through the user at the second location;
- analysing the detected acoustic signal to determine if it is indicative of transmission of the applied acoustic signal through an authorised user based on a known bioacoustic signature of the authorised user;
- and
- for the at least two touch locations, determining which parts of the user's hand provide the touch contact;
- wherein selecting the first location and a second location comprises:
- identifying available transmission paths, for an acoustic signal, through the user between the parts of the user's hand which provide the touch contact;
- and selecting one of the available transmission paths.
A non-transitory computer readable medium comprising program instructions stored thereon for performing at least the following:
- causing determination of at least two locations at which a user touches a device;
- selecting a first location and a second location from the at least two locations to define a transmission path for an acoustic signal through the user;
- causing application of an acoustic signal to the user through the first location;
- causing detection of an acoustic signal transmitted through the user at the second location;
- analysing the detected acoustic signal to determine if it is indicative of transmission of the applied acoustic signal through an authorised user based on a known bioacoustic signature of the authorised user;
- and
- for the at least two touch locations, determining which parts of the user's hand provide the touch contact;
- wherein selecting the first location and a second location comprises:
- identifying available transmission paths, for an acoustic signal, through the user between the parts of the user's hand which provide the touch contact;
- and selecting one of the available transmission paths.
