Globally, the usage of social media has significantly increased and has become the most common way for people to deplete news. The easy sharing of multimedia content on social media has caused the fake news dimension, which threatens the stability as well as security of the society. Fake news detection (FND) in social media becomes challenging, because of which various tools are developed to detect them. Multimodal FND aims to determine fake data by text as well as images. Most commonly, researchers identify fake news only as text, but not as images. This research proposes a multimodal method for the detection and classification of fake news into real or fake. The proposed multimodal-based convolutional neural network (CNN) combines the designs of both text and image of fake news. This method utilizes two classification methods named hyperparameter tuning based bidirectional encoder representations from transformers (HTBERT) for text, and ResNet110 for images. Fakeddit dataset has used to estimate and evaluate the performance. The experimental results of the proposed ResNet110+HTBERT model achieves respective accuracy, precision, recall and F1-score values of about 0.931, 0.944, 0.942, and 0.946, which is superior when compared to the existing methods, recurrent CNN (RCNN) and fine-grained multimodal fusion network (FMFN). From the analysis, it is evident that the proposed method ResNet110+HTBERT achieves an accuracy of 0.931, and hence shows better results for overall metrics when compared to the existing methods of RCNN and FMFN.
