A method comprising: receiving an access request for a video service from a client device; authorizing the client device to access the video service when the client device is initiating connection to the video service via a home Internet access point located in a home associated with an authorized account for the video service, wherein the video service is provided from a video service provider to the client device through the home Internet access point; determining a time restriction for access to at least part of the video service when the client device is initiating connection to the video service via a non-home Internet access point located outside of the home, a duration of the time restriction being dependent upon a usage behavior of the video service by the client device, wherein determining the time restriction comprises comparing the usage behavior of the client device to a first expected usage behavior model to determine the duration of the time restriction; and authorizing the client device to access the at least part of the video service from the video service provider subject to the time restriction when the client device is initiating connection to the video service via the non-home Internet access point; characterized in that comparing the usage behavior comprises: computing a score reflecting a similarity of the usage behavior of the client device to the first expected usage behavior model, wherein the score comprises a function of a distance between the usage behavior of the client device and the first expected usage behavior model; and computing the time restriction with the score as an input. receiving an access request for a video service from a client device; authorizing the client device to access the video service when the client device is initiating connection to the video service via a home Internet access point located in a home associated with an authorized account for the video service, wherein the video service is provided from a video service provider to the client device through the home Internet access point; determining a time restriction for access to at least part of the video service when the client device is initiating connection to the video service via a non-home Internet access point located outside of the home, a duration of the time restriction being dependent upon a usage behavior of the video service by the client device, wherein determining the time restriction comprises comparing the usage behavior of the client device to a first expected usage behavior model to determine the duration of the time restriction; and authorizing the client device to access the at least part of the video service from the video service provider subject to the time restriction when the client device is initiating connection to the video service via the non-home Internet access point; characterized in that comparing the usage behavior comprises: computing a score reflecting a similarity of the usage behavior of the client device to the first expected usage behavior model, wherein the score comprises a function of a distance between the usage behavior of the client device and the first expected usage behavior model; and computing the time restriction with the score as an input. computing a score reflecting a similarity of the usage behavior of the client device to the first expected usage behavior model, wherein the score comprises a function of a distance between the usage behavior of the client device and the first expected usage behavior model; and computing the time restriction with the score as an input.
