a memory device coupled to the processor; and a computer readable storage device coupled to the processor, wherein the storage device contains program code executable by the processor via the memory device to implement a method for filtering digital images stored on a blockchain database to locate one or more specific digital images from a corpus of digital images from an event, the method comprising: receiving, by a processor of a computing system, a search criteria from a user for searching through the corpus of digital images stored on the blockchain database, wherein digital data associated with each digital image is uploaded to the blockchain database by a digital data capturing device after the digital data capturing device appends metadata to the digital data at a time of creation of the digital data that defines a plurality of factors associated with the digital image; filtering, by the processor, the corpus of digital images stored on the blockchain database based on the plurality of factors that match the search criteria; locating, by the processor, the one or more specific digital photographs that match the search criteria among the corpus of digital images stored on the blockchain database, as a function of the filtering; presenting, by the processor, the one or more specific digital photographs to the user for selection and purchase of the one or more specific digital photographs, and processing, by the processor, a purchase order for the one or more specific digital photographs selected for purchase by the user. ### Claim 9 (depends on 8) The computer system of claim 8, wherein the plurality of factors includes a date, a capturing device identification information, an image identification, an image owner, a timestamp, a dynamic geolocation, a camera lens angle, a field of view direction, a beacon area, a geofence, a point of interest, a context surrounding the digital image, and a person of interest. ### Claim 10 (depends on 9) The computer system of claim 9, wherein the dynamic geolocation is a location of an event that is being photographed by at least one photographer. ### Claim 11 (depends on 8) The computer system of claim 8, further comprising: tagging, by the processor, a context to the corpus of digital images stored on the blockchain database using a machine learning visual recognition engine, wherein the search criteria that includes only the context results in digital images not containing the context being excluded from the corpus of digital images prior to the filtering to reduce a number of digital images to be filtered, decreasing a time between receiving the search criteria and the locating of the one or more specific digital photographs. ### Claim 12 (depends on 8) The computer system of claim 8, further comprising: performing, by the processor, a facial recognition technique using a facial recognition software on the corpus of digital images stored on the blockchain database, in response to receiving the search criteria including a person of interest, wherein digital images not containing the person of interest are excluded from the corpus of digital images prior to the filtering to reduce a number of digital images to be filtered, decreasing a time between receiving the search criteria and the locating of the one or more specific digital photographs. ### Claim 13 (depends on 9) The computer system of claim 9, wherein the beacon area is a physical area of the dynamic geolocation that defines a specific location of interest within the dynamic geolocation. ### Claim 14 (depends on 8) The computer system of claim 8, wherein the digital data capturing device is a device that has a network interface controller for uploading the digital data and metadata to the blockchain database, and is selected from the group consisting of: a digital camera, a smartphone, a smartwatch, a tablet computer, smart glasses, a fixed camera, a recorder, and a video camera. ### Claim 15 A computer program product, comprising a computer readable hardware storage device storing a computer readable program code, the computer readable program code comprising an algorithm that when executed by a computer processor of a computing system implements a method for filtering digital images stored on a blockchain database to locate one or more specific digital images from a corpus of digital images from an event, the method comprising: receiving, by a processor of a computing system, a search criteria from a user for searching through the corpus of digital images stored on the blockchain database, wherein digital data associated with each digital image is uploaded to the blockchain database by a digital data capturing device after the digital data capturing device appends metadata to the digital data at a time of creation of the digital data that defines a plurality of factors associated with the digital image;
