Mvc.net app to read a text from image and save it in the database

Gul Gul

I am new in this field.

How to create mvc.net app that the user will have a page to upload from it his id card and his passport? Then using mvc it should read the information that written in the image like(his name, id number, expiration date). and will save this information in the database for the user himself record using the id number as a key in the tables.
then the user should have another page to see the returned information from the uploaded images and the details from the active directory should be auto populate for him like his name and his id number and he should sign in using the active directory.

the uploaded image should be save in a file with a specific name"username-idnumber-idcard". Then before the expiration date of the card"the application should send a reminder email for the user to update his card and he should upload it again from the app". When he upload the card again , the image on the file should be replaced by the new one, and the data in the page and in the database should be updated. How to do this app step by step as I am new in this field.
If there is any similar topic or a ready mvc application that do this functionality please don't hesitate to put it here.

Thanks in advance..

You can use the IDFrameReader and the MRTDReader class to read both an ID card and a passport. This will allow you to get the string data which you can then move to your database.
using (IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.LEAD))
               {
          ocrEngine.Startup(null, null, null, null);

                  // Load the image
                  using (RasterImage rasterImage = codecs.Load(tempFile, page))
                  {
                     var engine = System.IO.File.ReadAllBytes("LEAD.Binarize.bin");
                     var reader = new IDFrameReader(engine, ocrEngine);

                     if (reader.Process(rasterImage).Ready)
                     {
                        //int index = 0;
                        foreach (var result in reader.Results)
                        {
                           {
                              // Get data
                           });
                        }
                     }
                     // Shutdown ocr engine
                     ocrEngine.Shutdown();
                  }
               }

You need to use congnitive service for this.
https://azurelessons.com/extract-text-from-image-azure-cognitive-services/

sample code.
// put your Cognitive Service Key1 value
static string Key = "12c9e662d55547779ce9785985932118";
// put your Cognitive Service URL
static string url = "https://mynewcognitiveservices91.cognitiveservices.azure.com/";

    static void Main(string[] args)
    {
        var client = new ComputerVisionClient(new ApiKeyServiceClientCredentials(Key));
        client.Endpoint = url;

        var myfile = File.OpenRead(@"C:\Users\Bijay\Desktop\VM\Bill\mybill2.jpg");
        var result = client.RecognizePrintedTextInStreamAsync(false, myfile);
         result.Wait();

        var rst = result.Result;
        foreach (var r in rst.Regions)
        {
            foreach (var t in r.Lines)
            {
                foreach (var w in t.Words)
                {
                    var coordinates = w.BoundingBox.Split(',');
                    Console.WriteLine($"Found word {w.Text} at" +
                    $" X {coordinates[0]} and Y {coordinates[1]}");
                }
            }
        }
    }
At last, you can save it into database.
