Digital image analyzing system involving client-server interaction

A method comprising:

• based on a printed medium of a physical item, generating, by a mobile device, digital scan data that reflects a plurality of ingredients that are referenced on the printed medium;
• sending, over a computer network, from the mobile device to a remote server, the digital scan data or data that identifies the plurality of ingredients;
• for each ingredient of the plurality of ingredients, determining, by the remote server, a toxicity rating of said each ingredient;
• identifying a subset of the plurality of ingredients based on the toxicity rating;
• wherein the subset includes a particular ingredient;
• receiving, from the mobile device, physical information about a user of the mobile device;
• determining that the particular ingredient is associated with a first toxicity rating;
• based on the physical information about the user and additional data about the particular ingredient, determining a second toxicity rating, for the particular ingredient, that is different than the first toxicity rating;
• causing the subset to be displayed on a screen of the mobile device;
• wherein the method is performed by one or more processors of one or more computing devices.

One or more storage media storing instructions which, when executed by one or more processors, cause:

• receiving, over a computer network, from a mobile device at a remote server, digital scan data or data that identifies a plurality of ingredients;
• wherein the mobile device generated, based on a printed medium of a physical item, the digital scan data that reflects the plurality of ingredients that are referenced on the printed medium;
• for each ingredient of the plurality of ingredients, determining, by the remote server, a toxicity rating of said each ingredient;
• wherein a first ingredient in the subset has a first toxicity rating and a second ingredient in the subset has a second toxicity rating that is different than the first toxicity rating;
• identifying a subset of the plurality of ingredients based on the toxicity rating;
• causing the subset to be displayed on a screen of the mobile device;
• wherein causing the subset to be displayed comprises causing the second ingredient to be highlighted differently than the first ingredient.
