Blind hash compression

One or more non-transitory storage devices storing instructions that, when executed by one or more computer processors, perform operations comprising:

• serving, from a computer server system and to a plurality of different computing devices remote from the computer server system, web code and code for reporting status of the computing devices;
• receiving from one or more of the computing devices, first data that indicates a parameter of the one or more computing devices, the first data in a compressed format;
• receiving from one or more others of the computing devices, second data that indicates the parameter of the one or more others of the computing devices, the second data in an uncompressed format;
• and
• compressing the second data and comparing the compressed second data to the first data to correlate the first data to the second data,
• wherein the code for reporting status of the computing devices includes code for allowing the computing devices to determine whether to send the first data or the second data,
• wherein the code for allowing the computing devices to determine whether to send the first data or the second data comprises biasing data that affects a frequency with which the computing devices select to send the first data or the second data.

A system of one or more computers, comprising:

• a first data communication interface arranged to communicate with a web server system;
• a second data communication interface arranged to communicate with clients that request content from the web server system;
• a compressed code interpreter programmed to identify an original form of compressed content received from particular ones of the clients by (a) compressing original content received from other ones of the clients to form a compressed representation, and (b) comparing the compressed representation to the compressed content received from the particular ones of the clients,
• wherein the compressed code interpreter compresses the original content using a technique that matches techniques used by the particular ones of the clients to compress the content,
• wherein the system is further programmed to provide code to the clients that allows the clients to determine whether to provide compressed content or instead, uncompressed content to the system,
• wherein the code for allowing the clients to determine whether to provide compressed content or instead, uncompressed content to the system comprises biasing data that affects a frequency with which the clients select to provide compressed content or uncompressed content to the system.

A computer-implemented method comprising:

• serving, from a computer server system and to a plurality of different computing devices remote from the computer server system, web code and code for reporting parameters of the computing devices;
• receiving from different ones of the computing devices, a plaintext representation of a particular parameter of a first of the computing devices, and a hashed representation of the same parameter of a second of the computing devices;
• hashing the plaintext representation of the particular parameter to create a hash value, and comparing the hash value to the hashed representation;
• and
• based on a determination that the hash value matches the hashed representation, correlating the hashed representation to the plaintext representation on the computer server system,
• wherein the code for reporting parameters of the computing devices includes code for allowing the computing devices to determine whether to send a plaintext representation or a hashed representation,
• wherein the code for allowing the computing devices to determine whether to send a plaintext representation or a hashed representation comprises biasing data that affects a frequency with which the computing devices select to send a plaintext representation or a hashed representation.
