US 2022/0019480 A1 · METHOD AND SYSTEM FOR SECURE DISTRIBUTED SOFTWARE-SERVICE

Abstract

A method and a system for securely applying proprietary software functions of software sources to proprietary data of a population of users are disclosed. The proprietary data of a user is not exposed to software sources, and the proprietary software of a software source is not accessible to users. A collaboration software module, placed in at least one cloud, is configured to establish, and continually update, a data structure holding task permissions from grantors to grantees, a grantor being a software source or a user, and a grantee is also a software source or a user. The collaboration software module of a cloud applies software function of a software source, communicatively coupled to the cloud, to proprietary data of an originating user, communicatively coupled to the same cloud, to produce a requisite result which is only accessible to the originating user or any grantees of the originating user (the grantor).

Claims20

Dependent claims

A method of secure software activation, comprising:

receiving, on a server system, from a first client in a plurality of clients, a request to perform a task using the server system,
receiving, on a cloud system hosting a collaboration software module, from the first client, a set of raw data associated with the first client;
accessing, on the server system, a library of user-defined functions (UDFs);
identifying, on the server system, a set of UDFs in the library applicable to said task;
embedding an encryption key into the set of UDFs to produce a set of secure UDFs;
sending, from the server system to the cloud system, the secure UDFs and a first identifier of the first client;
executing, with a processor of the cloud system configured to provide a collaboration software module, processes of:
determining that the first identifier matches a known cloud identifier of the first client;
upon a determination that the first identifier matches the cloud's known identifier of the first client, applying the set of UDFs to the raw data;
placing a result of said applying in a memory space of the cloud and making the result accessible to the first client;
and
receiving and granting an access request from the first client to access the result based on the first identifier.

9 more elements

A network for secure sharing of software applications among a plurality of clients, comprising:

a cloud hosting a collaboration software module;
and
a software provider configured to maintain a library of user-defined functions (UDFs) and configured to:
receive a request to perform a task from a first client;
identify a set of UDFs applicable to the task;
embed an encryption key into the set of UDFs to produce a set of secure UDFs;
and
send the secure UDFs and a first identifier of the first client to the cloud;
the collaboration software module being configured to cause a processor of the cloud to:
apply the set of UDFs to raw data of said first client placed in said cloud to produce requisite information subject to a determination that the first identifier matches a cloud's known identifier of the first client;
place the requisite information in a memory space of the cloud;
and
permit the first client to access the requisite information based on the first identifier.
