Abstract

Disclosed herein are methods for protecting user information on a client device that may have a plurality of users. A user interface with a public machine designation portion is presented to a user prior to the start of the authentication process. The public machine designation removes web service account descriptions and any user specific information stored on the client device. Also, the client device is prevented from storing any new user specific information that is provided to the client device. The public machine designation is a persistent feature that may only be disabled by an affirmative action from the user.

Claims

1. A computer memory comprising computer executable instructions that, when executed, direct a client device to:

receive user submitted input through a user interface on the client device, designate, based on the user submitted input, the client device as a public machine prior to user authentication;

remove a plurality of web service account descriptions stored for the client device corresponding to web service accounts with a plurality of service providers, the web service account descriptions being locally generated and used to generate a login user interface having at least one portion corresponding to each web service account of the web service accounts, the web service account descriptions being accessible to the client device to output the login user interface and selectable to cause authentication of the client device to the each web service account;

prevent the client device from storing web service account descriptions;

store a public machine designation in a browser readable object associated with the client device, the public machine designation being generated by the client device, the storing the public machine designation enabling the client device to prevent storing web service account descriptions until the public machine designation is deselected; and

disable a remember option for authentication data for the web service accounts with the plurality of web service providers.

2. The computer memory as recited in claim 1, wherein the descriptions include references to user customized data associated with the web service accounts.

3. The computer memory as recited in claim 1 further comprising instructions directing the client device to remove the designation as a public machine.

4. A method comprising:

under control of one or more computing systems configured with executable instructions,

designating a client device as a public machine prior to user authentication; and

in response to the designation;

removing access to customized user information that is stored for the client device and corresponds to web service accounts associated with one or more service providers, the customized user information including user credential data and user preferences for text and graphics, the customized user information being locally generated and enabling to generate a user interface that has at least one portion corresponding to each web service account of the web service accounts, the customized user information being accessible to the client device to output the user interface and selectable to cause authentication of the client device to the each web service account;

clearing the customized user information currently stored on the client device,

preventing the client device from storing the customized user information, and

storing a public machine designation in a browser readable object associated with the client device, the public machine designation being generated by the client device, the storing of the public machine designation enabling the client device to prevent storing the customized user information until the public machine designation is deselected; and

disabling a remember option for authentication data for the web service accounts associated with the one or more web service providers.

5. The method as described in claim 4, wherein the customized user information is accessible to the client device from storage on a server via a network.

6. The method as described in claim 5, wherein the client device utilizes locally stored descriptions of the web service accounts to determine where to obtain the customized user information.

7. The method as described in claim 6, wherein the removing access comprises deleting the locally stored descriptions.

8. The method as described in claim 4, wherein the removing access comprises deleting the customized user information stored on the client device.

9. The method as described in claim 4, wherein the customized user information comprises user selections from a group consisting of:

a user tile;

a user name;

an alias;

text;

graphics;

a color selection;

audio;

an image;

animation; and

video.

10. A method as recited in claim 4, further comprising:

storing on a client device descriptions of the authentication data corresponding to the web service accounts, wherein each the portion is selectable to cause communication of corresponding authentication data to authenticate the client device to the respective web service account; and

in response to the designation, removing the descriptions of the authentication data from the client device.
