Abstract

Techniques for data modification detection are disclosed. Descriptive information, including a resource identifier and a set of descriptive elements having a schema of representation, is received from a resource. Further, elementary information, including at least one of elementary resource identifier and set of elementary descriptors having an elementary schema of representation, corresponding to the resource is retrieved from a resource inventory database. A preliminary assessment is performed to assess similarity between the schema of representation and the elementary schema of representation. If the schemas are ascertained to be similar, a subsequent check is then performed to deduce a similarity between the set of descriptive elements and the set of elementary descriptors. Based on the subsequent assessment, an information-variance signal is generated to trigger rendering of an indication to indicate a probable modification of the set of descriptive elements in comparison with the set of elementary descriptors.

Dependent claims

A system comprising:

a processor to:
receive a data transmission from at least one resource amongst a set of resources, the data transmission comprising descriptive information associated with the at least one resource, the descriptive information indicating at least one of a resource identifier uniquely identifying the at least one resource and a set of descriptive elements providing an insight about one or more aspects related to the at least one resource, wherein the set of descriptive elements has a schema of representation;
retrieve, from a resource inventory database, elementary information corresponding to the at least one resource, wherein the elementary information is an instance of the descriptive information available in the resource inventory database prior to reception of the data transmission from the at least one resource, the elementary information comprising at least one of:
an elementary resource identifier uniquely identifying the at least one resource;
and
a set of elementary descriptors providing an insight about the one or more aspects related to the at least one resource, wherein the set of elementary descriptors has an elementary schema of representation;
perform, in response to the retrieval of the elementary information, a preliminary assessment of similarity between schemas of the received descriptive information and the retrieved elementary information, the preliminary assessment being performed by comparing:
the schema of representation of the set of descriptive elements associated with the at least one resource;
and
the elementary schema of representation of the set of elementary descriptors associated with the at least one resource;
ascertain, based on the preliminary assessment, whether to perform a subsequent assessment of similarity between the received descriptive information and the retrieved elementary information;
perform, based on the ascertaining, the subsequent assessment by deducing a similarity between the set of descriptive elements and the set of elementary descriptors corresponding to the at least one resource;
and
generate, based on the subsequent assessment, an information-variance signal to trigger rendering of an indication to indicate a probable modification of the set of descriptive elements in comparison with the set of elementary descriptors corresponding to the at least one resource.

A method comprising:

receiving a descriptive information associated with a resource from amongst a plurality of resources, the descriptive information indicating at least one of a resource identifier uniquely identifying the resource and a set of descriptive elements providing an insight about one or more aspects associated with the resource, wherein at least one of the resource identifier and the set of descriptive elements has a schema of representation;
obtaining, from a resource inventory database, elementary information corresponding to the resource, the elementary information comprising at least one of:
an elementary resource identifier uniquely identifying the resource;
and
a set of elementary descriptors providing an insight about the one or more aspects related to the resource, wherein at least one of the elementary resource identifier and the set of elementary descriptors has an elementary schema of representation;
comparing the schema of representation, of at least one of the resource identifier and the set of descriptive elements associated with the resource, with the elementary schema of representation, of at least one of the elementary resource identifier and the set of elementary descriptors associated with the resource, to assess a preliminary similarity between the schema of representation and the elementary schema of representation;
ascertaining, based on the comparison, whether to determine a subsequent similarity between the received descriptive information and the retrieved elementary information;
determining, based on the ascertaining, a similarity between at least one of:
the resource identifier and the elementary resource identifier corresponding to the resource;
and
the set of descriptive elements and the set of elementary descriptors corresponding to the resource;
and
generating, based on the determination of similarity, an information-variance signal to cause rendering of an alert for indicating a probable modification of the descriptive information in comparison to the elementary information corresponding to the resource.

A non-transitory computer-readable medium comprising instructions being executable by a processing resource to:

receive descriptive information from a resource associated with a network comprising a plurality of resources, the descriptive information indicating at least one of a resource identifier uniquely identifying the resource and a set of descriptive elements providing an insight about one or more aspects related to the resource, wherein the set of descriptive elements has a schema of representation;
obtain, from a resource inventory database, elementary information corresponding to the resource, wherein the elementary information is an instance of the descriptive information stored in the resource inventory database before reception of the descriptive information from the resource, the elementary information comprising at least one of:
an elementary resource identifier uniquely identifying the resource;
and
a set of elementary descriptors providing an insight about the one or more aspects related to the resource, wherein at least one of the elementary resource identifier and the set of elementary descriptors has an elementary schema of representation;
perform, in response to the obtaining the elementary information, a preliminary assessment of similarity between the received descriptive information and the retrieved elementary information by comparing:
the schema of representation of the set of descriptive elements associated with the resource;
and
the elementary schema of representation of the set of elementary descriptors associated with the resource;
ascertain, based on the comparison, whether to perform a subsequent assessment of similarity between the received descriptive information and the retrieved elementary information;
determine, in response to ascertaining to perform the subsequent assessment, a similarity between at least one of:
the resource identifier and the elementary resource identifier corresponding to the at least one resource;
and
the set of descriptive elements and the set of elementary descriptors corresponding to the resource;
and
generate, based on the determination of similarity, an information-variance signal for indicating modification of the descriptive information in comparison to the elementary information.
